• use the tools of geography to find and organize geographic
information, and to share your ideas with others
• use the themes of geography to study environmental

1 Our blue-green planet is our


place in space. Each of us has a
place on Earth. What are some other
“places” you have in your world?

2 Areas of rock like this along the shores of Georgian Bay in


Ontario are found in many regions of the world. This is layered
sedimentary rock. It shows that this region used to be covered
by a sea for millions of years. Describe the region around your
community. Tell about any special physical features.

3 There are large populations of ethnic groups in many large


cities of the world. Cultural regions, such as Chinatown in Toronto,
Ontario, make cities more interesting places to live. From which
countries have immigrants to large Canadian cities come?

bikes got more road lanes than cars
in their movement systems. Why do
you think this was so?

5 Someday, you will probably


want to own a car. What changes
do you think will have happened
in our traffic patterns?

6 Many introduced species have entered environments around


the world because of human activities. This lamprey eel found its
way into the Great Lakes through the St. Lawrence Seaway. What
problems might introduced species cause to plants and animals?

7 We value magnificent forests, like this


one near Temagami, Ontario, for timber,
wilderness, and recreation. The effects of our
interactions with such precious regions often
threaten to ruin them. How can we use such
forests now, while making sure that they
will be there for our children’s children?

with this growing mass of waste?

tens of billions of galaxies in the universe. Is it possible to truly

Where does it end? In the vastness of the universe, how important
is one human being? Before you answer, think about it. Each one
of us is important on Earth. Each one of us can make a difference

said to run north to south through the middle of North America. This
statement is approximately correct. However, it is far from precise.

understandings. For example, the Interior Plains of North America are
said to run north to south through the middle of North America. This
statement is approximately correct. However, it is far from precise.

Physical Factors
There are many reasons why places are located where they are.
Physical characteristics of the area affect where places are located.
It is important to consider the landforms. Are there hills, ridges, or
valleys? Bodies of water are also important. Is there a lake or a river
nearby? Well-drained soil makes a better location for a place than
soil that is poorly drained where flooding might occur. Vegetation,
weather, and climate also affect where places are located. Is the area
forested, or is it grassland? Is it cold or hot, wet or dry?

that do not belong on the list.

Human Factors
Other places were chosen for their location based on human char-
acteristics. People tend to locate where there are other people. Large
cities attract people. If there is a river or lake, communities tend to
spread along the riverbank or the lakeshore. People tend to live with
people of a cultural group similar to their own. Religious reasons can
also affect where people choose to live. Some people want to live
near the centre of their faith, like Jerusalem or Mecca.
Locations for places like towns, farms, or factories are chosen
because of distinctive human and physical characteristics. These dif-
ferent characteristics allow us to distinguish places from each other.

What’s in a Place Name?


Everyone sees the world differently. Our local place names reflect our
culture. We see many names that show ties to the First Nations peoples
who first lived in what is now Ontario. The list includes such names as
Algonquin Park, Mohawk Road, and the Lake Iroquois shoreline.
When we see places in other lands, we view them through our
own experiences and culture. The way we see such places may be quite
different from the way the people who live there see them. When we
look at a world map, it nearly always has the Atlantic Ocean near the
centre. We are seeing the world from our viewpoint.

Climate, Vegetation, and Soil Regions


Natural forces define climate regions, vegetation regions, and soil
Range of Vegetation,
regions. These three types of regions usually have the same bound-

aries. This is no accident. The climatic conditions of a region affect across North America
the types of vegetation that can grow there (for example, cactuses
or cattails). The climate and vegetation affect the soils that
develop. A specific climatic region will produce a spe-
cific vegetation region. In turn, the vegetation region Baker Lake
helps make a specific soil region.
Soil regions have similar patterns to geologic,
landform, and climate regions. A polar region has
a cold, dry climate — a cold desert. It is a region that has
little vegetation and very poor soil. A tropical region has a SW

Human Regions
Human regions are defined by human characteristics, such as how
many people live closely packed into a region. Cities are regions with
a high population density. Rural areas are regions with low popula-
tion density. Other ways to form human regions include culture
(language, religion, customs), political boundaries, or time zones.
A region can be defined in more than one way. For example,
the province of Québec has political boundaries, so it is a political
region. It is made up of mainly French-speaking people, so it is also
a cultural region.

A region could be defined by ski resorts (human) and mountains
(physical), or it could be defined by farms (human) and plains
(physical). When we combine natural features and human activities
in a particular area, we create a region called an ecozone.
The Riviera region along the north Mediterranean seacoast is
an ecozone. It includes parts of several countries (political regions).
These parts all have beaches and coastal mountains. They also have a
climate that is generally warm and dry all the time (physical region).
Similar kinds of crops are grown — grapes and olives (agricultural
regions). It has summer year round, so the area has become popular for
holidays (human region). All of these things together have made the
area a unique ecozone.

Latitude and longitude are commonly used as boundary


lines. Many other features are used as well. Roads and
settlement patterns, such as survey lines for county
boundaries, act as boundaries. Distance limits from shore-
lines are used by countries to put boundaries around fish-

Latitude and longitude are commonly used as boundary


lines. Many other features are used as well. Roads and
settlement patterns, such as survey lines for county
boundaries, act as boundaries. Distance limits from shore-
lines are used by countries to put boundaries around fish-
eries. A country will even include the air above it as its fly
zone or region, and other countries must ask permission N
to fly through this air space.

Weather Changes Regions


Sometimes changes in the weather patterns in another area of the
world can cause changes in our regions. Amazingly, the pattern of
ocean currents over 8000 kilometres away affects our lives here in
Ontario. El Niño is a huge mass of very warm water. It appears
frequently off the coast of northern South America. Since 1985,
such episodes have happened in 1986, 1991, 1993, 1994, 1997–98,
and 2002.
It is difficult to predict what effect an “El Niño year” will have
on the weather in North America. However, these episodes can
result in more storms, higher precipitation, and more extreme
seasonal temperatures.

Hurricane Increase
In the past decade, more frequent and more intense hurri-
canes and tropical storms have affected North America and
the Caribbean. Many people believe that global warming
and effects like El Niño are to blame. In 2005, Hurricane
Katrina brought great devastation to the Gulf of Mexico
coast in the United States, especially to New Orleans. By
2007, New Orleans still needed more reconstruction despite
the tremendous efforts of governments and citizens.

Figure 2.34
This is a photograph of
Hurricane Frances, which
struck the coast of Florida
in September 2004. The
strongest El Niño on record
was in 1997–98. In that winter,
western Canada was unusually
warm, and the southern and
western parts of the United
States suffered many storms.
How do you think El Niños
have affected Ontario?

Figure 2.35
This is what a neighbourhood in
New Orleans, Louisiana, looked
like shortly after Hurricane Katrina.
Although billions of dollars have
been spent to provide protection
from future storms and to rebuild,
the future effects of climate change
are still hard to predict accurately.

Road Systems
A wide range of road systems exists to accommodate the various
vehicles we use. Roads range from narrow dirt lanes to complex net-
works of expressways. The scale and quality of the road system in a
place depends on its nearness to areas of high population, markets,
and other large centres.

Pipe It On Through
Most of us are unaware of how much we rely on pipelines. Every
time you get water from a drinking fountain or flush a toilet, you
use a pipeline. We use pipelines to move water, waste, oil, gas,
chemicals, and coal. Foods such as grains (mixed with a liquid) can
be pumped through pipelines.
Pipelines have several advantages. Materials move continuously
with little labour involved. The movements are direct from point to
point and require little maintenance. The big problem is the cost of
installation.
Large pipelines (up to 120 centimetres in diameter) move oil in
huge quantities. In Canada, our largest pipeline is the Interprovincial

Trading around the World


Resources are not equally distributed around the world. For example,
Australia has a lot of bauxite (aluminum ore). Canada has no bauxite,
but it has a lot of hydro power to make the bauxite into aluminum.
This establishes a basis for trade. We import bauxite, use our hydro
power to make it into aluminum, and then export aluminum. Once a
basis for trade is established, movement of products will occur.

Fresh water is critical to all life on Earth. Farmers need fresh water to

the oceans (desalination), but the technology is complicated and
very expensive.

Give and Take


The plants and animals of an ecosystem are all struggling to survive.
To be successful, each plant or animal makes use of special features
that allow it to take what it needs from the ecosystem. Plants use
their roots and leaves to get nutrients, while animals and birds use
their legs, talons, or teeth.

Omnivores very few Figure 4.9

Each member of an ecosystem also adds something to the system.


Small animals are the food source for larger animals. Some organisms
such as earthworms loosen soil by burrowing through the layers. The
decay of all organisms adds to the soil’s fertility. A rotten, hollow tree
becomes a home for squirrels and raccoons. Beaver dams make better
environments for fish by creating natural ponds. This give-and-take
is vital to the health of the ecosystem. Changing any one part of
an ecosystem changes the whole. No matter how small, any change
causes a ripple effect that impacts the entire ecosystem.

Food Pyramids and Webs


The key to all life on Earth is the Sun. The Sun provides warmth. It
gives the energy used by plants to make their food. Plants use solar
energy to change water and carbon dioxide into a kind of sugar that
they use as food for growth. This process, called photosynthesis,
produces oxygen as a by-product. Since most animals need oxygen
to survive, they are dependent on plants.

A food web is a complicated feeding relationship between producers, herbivores, carnivores,
and omnivores. Nearly all species feed on more than one type of food. This makes the food web
very complicated. Any toxic (deadly) chemicals eaten by one species will be passed along to the
others. The higher on the food pyramid a species is, the more of these toxic chemicals it eats.

The Balance of Nature
Each ecosystem can support only a limited number
of plants and animals in a close relationship.
A good example of this can be found in wolf-
management plans. If wolves are removed, the deer
population rises. The deer then overeat the local
plants, especially young and low-growing trees.
Soon, even that food source is gone. Weakened by
the lack of food, the deer are more likely to die from
disease, from exposure to cold, or by being eaten
by predators. Some deer might move to another
area with a better food supply. Over time, predators,
disease, and migration reduce the size of the deer
herd. Changes to any part of the system can upset
the delicate balance of nature.
Humans are a huge part of many food webs. There
are so many people on Earth that our needs for food
and other resources have seriously affected many food
webs. The result is that many life species have become
extinct. That is, they no longer exist anywhere on
Earth. As well, many species are endangered, or at
risk of becoming extinct.

Value 4 — Intrinsic Value


We are amazed by the creatures that surround us. We have pets. We
create zoos, aquariums, and special gardens to visit and enjoy. Many
people camp, canoe, and hike for leisure and recreation. Obviously,
we care about plants, birds, insects, fish, and other animals (and
their habitats) apart from any use they may have for humans.

Fragile Ecosystems
Ecosystems are constantly changing. As the climate changes, an
ecosystem may get drier and drier. Vegetation that prefers drier
conditions will do well and gradually become dominant. Trees and
plants that need more water will die off. Wildlife that can stand a
drier environment will increase.
Some ecosystems can handle change better than others. Ecosystems
that are drier and cold tend to be more fragile than others. They have
more difficulty handling changes. These ecosystems have fewer species.
When a change occurs, they have fewer choices to fall back on.
The tundra is a good example of a fragile ecosystem. It is both
cold and dry, with a very limited number of species. Suppose a
predator has only two animals on which it feeds. If one of these is
drastically reduced in number, many of the predators will starve.
This kind of change is much less likely in a warm, wet environment,
where there are far more species and very complex food webs.

How People See the Environment Differently


Have you ever seen ads on TV of someone driving a dune buggy
or jeep through a desert or over sand dunes? The message
of those ads is that those environments are there just
for our pleasure and that it does not matter if we
destroy some parts of these areas either know-
ingly or unknowingly. Many people will never
believe that. They know that a sand dune is
a special, delicate environment that can be
easily destroyed. They understand that deserts
and sand dunes are homes to fragile ecosys-
tems. Many animals live within a sand dune,
including fringe-toed lizards and sand snakes.

may be the only major alternative to growing
crops. In very wet areas, people may have to
wait for a dry season to grow crops, or they
may grow crops like rice that thrive in water.
Where it is too cold, agriculture is not
possible. Permafrost covers a very large part
of Earth, particularly across northern Asia,
Europe, and North America. In these areas, the
subsoil is permanently frozen, and only a thin
surface layer thaws in summer. Until recently,
people who lived in these areas got their food
mainly from herding reindeer, fishing, and
hunting caribou, seals, walruses, and whales.

The summer monsoon winds blast Bangladesh and bring heavy

The Physical Environment —


Challenge and Opportunity
People display an amazing ability to adapt to the physical environ-
ment. People use what the environment offers in these ways:

• Some people build snow houses, sod houses, leaf and thatch
houses, houses made from animal skins, log houses, and even
homes inside natural caves or cliff sides.
• Some people use trees to make canoes. Others use animals
and vegetation for going across snow and ice, or for moving
settlements.
• People adapt their surroundings to get food. Some people build
stone weirs, or fence traps in the water, to catch fish. Others
move water to irrigate farmland.

As times change, people’s methods
of living change as well. What
changes do you see in this photo
of a trapper in Nunavut?

Conflicting Viewpoints
Not every group of people sees the environment in the same way.
When Europeans entered North America, they placed a value on
furs that First Nations peoples and Inuit would have considered
foolish. First Nations peoples and Inuit used the furs they needed
for survival. The Europeans used the environment for its riches. First
Nations peoples lived with the environment. They used what they
needed, but they did not exhaust the resources.
In North Africa, local peoples lived more or less in balance
with their environment. They grew grains and raised animals. The
Europeans saw a chance to grow cash crops like peanuts. These crops
had high value, but growing them made the soil less fertile and more
easily eroded. Drought affected the soil more easily. The price of
growing cash crops became the environment.

We control our local environments through engi-


neering and technology. We add heat or cold to our
buildings and homes when we need it. We use
resources such as oil, natural gas, and coal to
produce electricity. We have learned to take
advantage of the Sun, moving water, the tides,
and the wind to provide power.
Big urban areas use up a lot of energy.
We have built power lines to move energy
from the power sources to cities and towns.

Waste Management
The artificial environments in our cities
waste a lot of energy. In recent years, we have
tried to use more energy-saving methods such
as better insulation, windows, heating systems,
and lighting. In spite of this, Canada is a world
leader in energy consumption. This is not a “number
one” that we want. We can all reduce the amount of
electricity we use. Just remembering to turn off the lights
will help a lot! Figure 5.22

When we look at the great mountains, the seashores,

The Continental Drift Theory


Continental Drift A German scientist, named Alfred Wegener, developed a theory
250 million years ago known as continental drift. He suggested that, at one time, all the
continents that we know today were one supercontinent, which
began to split up over 100 million years ago. The continents
have slowly moved apart over millions of years. Look at a

might have once fit together?

C H A P T E R 6 : Patterns in Natural Systems: Landforms 125

Landforms
We live on landforms, which are the natural
physical features of the land. Most humans live
on the flattest or gently rolling areas of Earth.
Our landforms are changing all the time due to
forces on and within Earth.

Volcanoes
Volcanoes are landforms created by magma
escaping from below Earth’s surface. Volcanoes
are erupting regularly and building new land on
our continents and in the oceans. There are over
900 active volcanoes in the world.

Figure 6.8
Located in Hawaii in the United States, Kilauea is the
most active volcano on Earth. It has been erupting
almost continuously for the past 25 years. Check an
atlas or the Map Appendix to find the volcano that
is closest to where you live.

Fold Mountains
Moving plates buckle, bend, and fold rock layers
upward to create fold mountains. When plates
collide, the resulting pressure forces the rock to
bend and rise up.

The Appalachian Mountains


of eastern North America
are examples of old fold
mountains. They extend
over 3200 kilometres, from
Newfoundland in the north
to Alabama in the south.
(See Map Appendix.)

Figure 6.9
These fold mountains are located in Banff, Alberta. The Canadian Rockies and the Himalayas
in south Asia are fold mountains. Can you see the bending in the rock layers? These mountain
ranges were once relatively flat layers of rock that built up on ancient sea bottoms.
126 U N I T 2 : Patterns in Physical Geography

Plateaus
A plateau region is formed when a fairly flat area in a mountain
region has been uplifted by plate movement. Plateaus are typically
flat high areas with steep sides.

Figure 6.10 Plateau


The central portion of the Western
Cordillera is a plateau. Plateaus are Mountain Mountain
usually quite high and flat with steep
sides. One of the world’s highest large
plateaus is in central Bolivia. Use an Ocean
atlas and find La Paz, Bolivia. What is
that capital’s elevation above sea level?

Shields
Shields are the original foundations
for our continents. Other landforms
were built upon them. Major world
shields include the Brazilian Shield,
the Central Massif of France, and the
Canadian Shield.

Figure 6.11
A shield is the base of an ancient
mountain region. The mountains
have been worn away leaving a

First Nations people would often stampede buffalo

2. Choose a landform from a continent of your choice from this
section (see Map Appendix), and research to find out more
about it. To begin, think about what you want to learn about this
landform on this continent, and record at least three questions
to guide your search (for example, How are different types of
valleys formed on this continent? What are the features of the
mountains found on this continent? How are the plains used
on this continent? Where are plateaus found on this continent?
How have the valleys on this continent changed over time?).
If you are using a search engine on the Internet to search for
answers, use key words from your questions as possible search
strings (for example, valley types formation Africa, or mountain
features South America, or plateau location Asia).

Mountains
Anything over 600 metres is generally considered to be a mountain.
Mountains present challenges to people in the following ways:

• It is difficult for people to settle on land that is so rough and


rugged.
• Transportation is a challenge. People must find a way between
the steep mountains.
• The harsher climate and the limited amount of topsoil in most
mountain regions make agriculture very difficult.

Several mountains clustered together as a group are called a


mountain range. When several ranges are grouped together, they are
called a mountain chain. The Himalayas and the Western Cordillera
are two of the largest and longest mountain chains in the world.
Mount Everest, in the Himalayas, is the highest peak in the world at
8848 metres high.
The Andes in South America continue from the Rocky Mountains,
which are part of the Western Cordillera. The Andes and the Rockies
are mountain chains that extend along the west coast of two con-
tinents. The southern side of Europe and south central Asia are also
mountainous. The most famous mountains in Europe are the Alps.

History Henry Hudson wanted to find a


passage from the Atlantic Ocean
to the east through North America. In
1610, he sailed into and explored the huge saltwater bay
now called Hudson Bay. That winter, supplies ran low,
and his crew mutinied. They set him, his teenage son,
and eight loyal crew members adrift in a small boat
on the icy waters of the bay. Captain Hudson and
that small band were never heard from again.
Eight of the mutineers survived the winter
and returned to England.

Great Lakes–St. Lawrence Lowlands


The third and smallest of Canada’s plains is the Great Lakes–
St. Lawrence Lowlands. It is the most densely populated part of
Canada. This small lowland region includes the southern portion of
Ontario between Georgian Bay and Kingston, and an area in southern
Québec along the St. Lawrence River. It is a relatively flat and easily
farmed region — a very prosperous area. The rivers in this area drain
into the Great Lakes and the Atlantic Ocean. These rivers have played
an important role in the development of settlement and industry.

The St. Lawrence Lowlands, mainly
east and northeast of Montreal,
were flooded by the sea after the
last Ice Age. When the sea moved
back, the St. Lawrence River

This daily change in outdoor conditions is called weather.
When we talk about weather, we usually describe the following:

• whether the Sun is shining or not Does this photograph show weather
• if there is any precipitation conditions or climate conditions?

NEL
C H A P T E R 7 : Patterns in Natural Systems: Climate and Vegetation 141

People may confuse weather with climate. Weather deals only with
short-term changes, while climate is long term. Climate refers to the
yearly patterns of precipitation and temperature that emerge when all
the daily weather patterns are combined.
Geographers look for patterns in the way temperatures and pre-
cipitation change over the year. Geographers study climate because
its patterns tell a great deal about places. Climate is one of the most
important factors influencing the vegetation found in a place.
Together, climate and vegetation shape the soils. The climate, vegeta-
tion, and soils of a place influence people and their activities.

Seasonal Changes
In Ontario, the seasons are spring, summer, fall, and winter. However,
in the north, there are really only two seasons — a long winter and
a short summer. In the tropics, the temperature is fairly constant
throughout the year, but there is a rainy season and a dry season.

Climate Graphs
To describe the climate where you live may seem like a difficult
task, but there is a simple and effective method. Climates can be
studied and compared by analyzing climate graphs. A climate graph
makes it easier to identify patterns because it combines two graphs.
Temperature is displayed using a line graph, and precipitation is
shown using a bar graph.

parts of Earth’s surface. Let us look first at global climate factors,
and then at local ones.

a larger area of Earth.
This unequal heating of Earth’s surface causes air to move from
one place to another, creating winds in the atmosphere and currents
in the oceans.

Global Climate Factor: Wind Systems


The air over the hotter parts of Earth is warmed by the heat from
the surface of the land or water. A heated air mass rises because it
expands as it warms. Cooler air slides in below and under the rising
air. These movements of air across Earth’s surface are called winds.
Since the equatorial areas are hot and the polar areas are cold,
would you expect the winds to always move along Earth’s surface
from the poles to the equator? This does not happen for two main
reasons: Earth rotates, and land and water are distributed unequally
around Earth’s surface.
Earth’s rotation on its axis from west to east creates a force that
causes the winds in the northern hemisphere to seem to swerve to the
right, and winds in the southern hemisphere to swerve to the left.
The unequal distribution of land and water around Earth’s sur-
face (for example, water at the North Pole and land at the South
Pole) means that the pattern of hot and cold is not uniform. These
two forces working together give a global circulation pattern of rising
and falling air masses.
Winds are the air movements that bring daily weather to your
area. The prevailing winds in an area are the winds that blow most
commonly for that particular area. Winds across
Canada generally blow from west to
east, so we call these winds the 90

Hurricanes grow out of tropical storms. Tropical storms form in late
summer over warm water. Heat causes air to rise, which rapidly
pulls in cooler air in a great spiral. When wind speeds are over
120 kilometres per hour, a storm becomes a hurricane.
Hurricanes move slowly, but they are very destructive when
they hit land. A good example of a dangerous hurricane was

Local Climate Factor: Mountain Barriers


Mountain barriers influence climate patterns. When moisture-bearing
winds meet mountains, they move up the windward sides of these
barriers. As the air rises, the reduction in air pressure causes the air to
cool. The cooler temperatures cause the moisture to condense. This
condensation produces clouds, and then rain. By the time the air
reaches the tops of the mountains, it has released most of its mois-
ture. This type of rainfall is sometimes known as relief precipitation,
or orographic precipitation.
Parts of the west side of British Columbia’s Coast Mountains
receive over 2000 millimetres of rain every year due to orographic
precipitation. As the air mass comes down the east side of the
mountain — the leeward side away from the wind — the air becomes
warmer and drier. The east side of these mountains remains dry. This
side may get as little as 300 millimetres of precipitation annually.

raise the temperature as much as 24 °C in as little as
15 minutes. This warming wind is called a chinook.

Local Climate Factor: Bodies of Water


Large bodies of water, such as oceans or lakes, take a long time to heat
up or cool down compared to the land around them. This is best seen
in the early winter when the ground is covered with snow, but lakes and
ponds are not yet frozen over. Temperatures in large bodies of water are
cooler in summer than the land nearby and warmer in winter.
A lake’s temperature affects the temperature of the land around it.
Temperatures in the Toronto area are warmer than the surrounding
areas in the winter because of the heat held in the lake. The Toronto
area is also cooler in the summer. Overall, the temperatures are more
moderate, or less extreme, than they would be without the lake.

Raindrops Keep Falling


Large bodies of water have an additional effect on climate. As an air
mass passes over a large body of water, it picks up moisture. When
the air crosses land, it may lose that moisture in the form of snow or
rain. Areas near large bodies of water often have more precipitation
than places not near water.

Most of the extra greenhouse gases are produced by burning fuels,


including coal, gasoline, and natural gas. These fuels are consumed
in vehicles, homes, factories, and stores. We rely on these fuels to live
modern lives with lots of comfort. Smaller amounts of greenhouse
gases are produced by activities such as the following:

• cutting and burning forests, especially tropical rainforests that


are being cleared to create farmland
• raising livestock like cows and pigs (their digestive systems
produce greenhouse gases)
• growing rice in paddies where the decaying plant material
produces greenhouse gases

2. What would the world be like if there were no soils? How would your
life change if all the soils in the world were used up and useless?

Soils
The type of soil in an area will help to determine the type of natural
vegetation and how well it grows. Soil contains moisture, air,
and organic material. It also contains vital minerals such as
phosphorous, potassium, and calcium that are necessary
for plant growth. To meet daily requirements,
vegetation relies on the minerals contained in
the soil. Unfortunately, not all soils are really
productive. Desert soils are often sandy and lack
nutrients. The sand is unable to hold water and
lacks organic material.

Topsoil Really Is Tops


To an extent, vegetation creates the soil in
which it grows. The plants die, and the decaying
plant material — humus — builds up in the top
layer. Nutrients are released slowly, to be cap-
tured by growing plants. Soils also get nutrients
from the weathered rock of the area. As the rock is

Drainage
Water drains from the highest point of land in an area to the lowest.
Rivers flow from the high ground to the low. Look at the map in
Figure 8.3. Can you see that rivers can flow downhill in different
directions? Some flow north, while others flow south. The higher land
that divides two different drainage basins and sends one river one way
and the other in a different direction is known as the divide.
The Oak Ridges Moraine, just north of Toronto, divides two
drainage basins. This moraine is the divide between rivers that drain
north to Lake Simcoe and rivers that drain south to Lake Ontario.
The Oak Ridges Moraine was created during the last Ice Age. The
ridge of sandy hills acts as a giant rain barrel for the Greater Toronto
Area. The sand and gravel of the moraine soak up rain and snow,
and allow it to move down into large underground natural reservoirs
called aquifers. Many communities dig wells into these aquifers for
drinking water. Recent development has threatened to destroy this
important physical feature and change the flow of the rivers that Figure 8.3

Major River Systems of the World


Every continent has several major river systems (see Map Appendix).
A river system is made up of the main channel of a river and all of
the tributaries that flow into it. These rivers drain large areas of land,
and they are often important features in many communities. Each
of the major river systems takes runoff from a continent and drains
into one of the oceans.

Fixing a Damaged River
The Trout River is a small river on Prince Edward
Island. It flows through an area of potato farms, a
crop for which Prince Edward Island is famous. The
red sandy soil of this part of the province is easily
eroded. The Trout River used to be murky with sed-
iment and polluted with pesticides that were used
on the crops. Fish had trouble surviving in the dirty
water. A group of volunteers started the Trout River
Environmental Committee (TREC) in 1993 to try
to save the river. Over the years, TREC gradually ex-
panded its interests. It now covers six watersheds
and over 150 kilometres of fresh water.
The committee’s first action was to stop the
soil from washing into the river. They planted
trees and shrubs along the banks to hold the soil
in place. They worked with local farmers to help
them reduce the amount of soil that washed off
their fields. They also built brush mats — clumps of
evergreen trees tied together — that they fastened
in the river. These brush mats trapped sediments
so that the water ran clear. Adding bird and bat

Drainage Patterns
All the tributaries that feed into the main channel form different
types of patterns called river drainage patterns. The drainage pattern
is affected by the underlying rock — the rock that the river flows
over. Different types of rock erode at different rates. Soft rock (for
example, limestone) erodes more easily and faster than hard rock
(for example, granite).
Dendritic drainage
Dendritic Drainage Pattern pattern
Most rivers have a dendritic drainage pattern.
Imagine a leaf, with all the veins connecting to
the main vein in the centre of the leaf. Think of
the main vein as being the main channel of the
river, and the small veins as being the tributaries.
Tributaries join the main branch of the river in
a V-shaped junction. The V points downstream,
toward the mouth of the river. Dendritic drainage
patterns usually occur in gently sloping areas
where all the underlying rock is about the same
hardness, so that it erodes or wears away in a uni-
form manner. Most of the rivers that drain into
Lake Ontario have a dendritic drainage pattern.
Trellis drainage
Trellis Drainage Pattern pattern
Some rivers have a trellis drainage pattern — a
rectangular pattern where the tributaries flow
perpendicular to the main branch of the river.
These tributaries are very often located where
there are bands or rows of hard rock and soft
rock. Tributaries travel along the areas that erode
faster (softer rock) and break through the hard
rock where they can.

The Industrial Revolution


The Industrial Revolution began in the late 1700s. It marked the
beginning of powered machines. Farmers gained new tools to help
them plow their fields and plant their crops. The Industrial Revolution
also brought improvements in transportation with new methods of
road building, the development of rail lines, and the invention of
the steam boat and steam locomotive. Agricultural products could be
moved from the country to the city quickly and easily. Because of the
new methods, farmers began to produce more food than they could
use. They could sell some of their produce. That was the beginning
of commercial farming.

flat or gently rolling topography. Others are faced with short growing
seasons, lack of rainfall, and steep slopes. People have adapted their
farming practices to suit their locations and climates. Different types
of agriculture are practised in different parts of the world. Three main
types of agriculture are subsistence, commercial, and specialized.

Subsistence Agriculture
In many parts of the world, farms can produce only enough food to
support the farmers and their families. Everything the family produces
goes toward feeding and providing for the household. Nothing is left
over to sell. Farmers usually have to plant a variety of crops to meet
their needs. This type of farming is called subsistence agriculture.
Subsistence farming exists in many developing countries. This is
often because the soil conditions are poor. This type of farming also
occurs in areas with harsh climates.

Figure 9.3

of power in subsistence agriculture.
What do you think that these
Vietnamese farmers are doing?

NEL
C H A P T E R 9 : Patterns from Interactions: Agriculture 185

Because of poor farming conditions, and the poverty that comes


from this, subsistence farmers cannot afford to buy modern technology.
They are forced to hold on to ancient practices. This makes producing
abundant crops even less likely. Farming becomes a terrible trap for
these people. They do not have enough to eat. There is no money to
make their farms better, so they get less and less as time goes by.

Tsaatan Nomads
The Tsaatan nomads live in a remote part of northern Mongolia. This
subarctic land of forests, lakes, and mountains is quite similar to some
parts of Western Canada. The people are subsistence herders who
depend on reindeer for their survival. The reindeer (called caribou in
North America) provide most of the raw materials for shelter, food,
and clothing. The Tsaatan live in teepees (similar to those of some of
the early North American First Nations) made from reindeer skins.

they live in large tents. The yaks are used to carry the few household
goods these farming families own. Farmers exchange yak butter and
wool for household goods in markets.
Dried yak dung is the basic fuel in this region. Children have the
task of collecting the dung from the fields for the cooking fires. The
dung is also traded for grain with neighbours.

Tea Plantations in India


India is famous for its tea plantations. These large farms have been
planted with bushes that produce tea leaves. Most of these plantations
are set on the Himalayan slopes and the fertile plains of northeast
India. Tea plantations in India are successful because of the rich soil
and high rainfall.

Specialized Agriculture
Specialized agriculture is a term used to refer to crops that are
produced only in certain places. Specialized agriculture is successful
because these crops or livestock require unique conditions that
are found in these locations. Pineapples, for example, require hot
temperatures and can be grown only in tropical countries. Citrus

Rice-Fish Farming
Rice-fish farming has been practised for centuries in China and
other southeast Asian countries. Most varieties of rice are grown
in flooded fields called paddies. The paddies are kept filled with
water for most of the growing season. Small fish are released
into the water and they live there until harvest time. These
fish feed on the weeds and other plants in the paddies that
would otherwise compete with the rice for sunshine, fertil-
izer, and nutrients. The fish droppings add to the fertility of
the soil and increase crop production. When the rice crop is
harvested, so are the fish.

Specialized Agriculture in Canada


Canada’s size means that there are many different types of
growing conditions. Because of this, Canada has many types
of specialized agriculture. Figure 9.20

Ginseng from the Okanagan Valley


Ginseng has traditionally been regarded as
a “miracle cure” in Asia. Today, ginseng has
become one of British Columbia’s most profit-
able specialized crops. The hot, arid region in and
around the Okanagan Valley provides desert-like
conditions. The ginseng root thrives in this rain
shadow because the hot and dry conditions reduce
the spread of fungus and root rot. Ginseng
requires a good deal of labour to grow and
harvest. Roof-like covers must be constructed
and maintained, and the ripe berries must be
picked by hand. However, its high market
value makes it a profitable crop.

Figure 9.23
Ginseng is not a traditional crop in the area, but it
grows well in the unique growing conditions of the
interior of British Columbia.

Supplying Our Demands


Natural resources come from our environment. Almost all natural
resources must be changed before we can use them. These changes
are called processes. One exception to this is some foods. We can eat
berries and nuts just as they grow in nature. No changes have to be
made before they can be eaten.

Processing Resources
To understand how resources have
to be processed, trace the steps in
making a pair of jeans. The natural
resource — the cotton — must first
be grown and picked. The cotton
bolls are then trucked to a mill
where the fibres of the boll are
wound together into cotton thread.
Large machines weave the indi-
vidual threads together into a
cotton fabric. The cloth is dyed
blue or black, or whatever colour is
popular, and shipped to a clothing
manufacturer. There, the fabric is
cut into shapes and sewn together
into a pair of jeans. Labels are put
on the jeans, and they are shipped
out to stores.

a pair of jeans is made. What does each
picture show about the process?

Advancing Technology
Humans have learned how to process natural resources to better meet
our needs. We use technology as a tool to modify resources. Technology
is the practical use of scientific knowledge to solve problems.
Technology has changed over time. As technology changed, our
use of natural resources also changed. Early humans used only plants
and animals to meet their clothing needs. Modern humans still use
plants and animals, but now we also use other natural resources that
require much processing, such as minerals and chemicals made from
petroleum. The use and processing of resources can affect the natural
environment, as you will learn in this unit.

Modern Technology
• Fabrics and coverings are made
out of human-made materials,
such as nylon and lycra.
• Raw materials include petroleum.
• A lot of processing is needed.

Growing Consumption
An important fact in our world is that most people want more things.
They want nice cars, trendy clothes, larger homes, more food, a lot
of electronic goods, and so on. The demand is growing for just about
every natural resource. Some experts think that between 2005 and
2055, the total amount of the world’s natural resources that people
consume, or use, will grow by at least 100 percent, and perhaps by
up to 500 percent. Energy consumption will be an important part of
this growth. Experts warn that non-renewable supplies like oil and
natural gas will eventually run out.

Concerns about Natural Resources


Many people are recognizing that their use of natural resources is
harming the physical environment. They are encouraging other
citizens and their governments to take actions that will help reduce
the use of resources and protect the environment. One action that
more and more Canadians are taking is buying hybrid cars that are
powered by both gasoline and electricity. This is one way that they
can reduce their consumption of energy.

Making Resources Last


How do we make our natural resources last for generations to come?
People must work to sustain them. The best way to do this is to
learn about how resources are used to provide you with the things
you need and want. We have to make sure that our way of life does
not use up non-renewable resources and does not waste renewable
resources. We all can make sure that we practise the 3 Rs — reduce,
reuse, and recycle — to the fullest extent possible.

You Are Important


As a consumer, you have a big role to play in helping to reduce, reuse,
and recycle. Think about the pop cans that you use. A large part of the
aluminum that is produced in the world is used for beverage and food
containers. Aluminum is made from bauxite, a mineral dug from the
ground. Not recycling aluminum pop cans means that the bauxite is
rapidly being used up. When it is gone, it will be gone forever. It also
means that more energy must be used to process the aluminum needed
to replace the pop cans. Making pop cans from recycled aluminum
takes only 5 percent of the energy that it takes to make pop cans from
bauxite. Recycling metals saves valuable non-renewable minerals, and,
therefore, energy. It helps to sustain our natural resources.

Figure 10.12
This table shows the proportion of energy saved by recycling materials. Why do you
suppose the amount of energy saved varies from one material to another?

The rainforest environment is lush and rich. Over 3500 mil-

Trees grow quickly in this climate. Growth is so lush that

Growing Food in a Forest


The Yanomami plant gardens to grow their food. Their system of
planting is known as shifting cultivation. Each family has its own
garden patch where they grow plantains (similar to bananas), bananas,
yams, manioc (a root vegetable), and sugar cane. They also grow non-
food crops — cane for arrow shafts, reeds whose sharp leaves are used
for cutting, and tobacco. After several years, weeds invade the gardens,
and the soil becomes exhausted. The Yanomami simply shift to a new
location and make a new garden.
To make a garden, the Yanomami must clear the dense forest, which
is a difficult task. They begin by choosing a site with good drainage and
soil. Small trees and underbrush are cut and piled to dry out and be
burned. Large trees are girdled — a strip of bark is cut off the trunk all the

and socializing take place in the central area.

Intruders in the Forest


The years since the 1950s have not been good for the Yanomami.
Outsiders searching for minerals and forest products brought dis-
eases such as tuberculosis with them. Many Yanomami, especially
babies, died. The infant death rate for the Yanomami is 13 percent,
compared to 1.5 percent for all of Brazil. Most frighteningly, the out-
siders are killing the Yanomami in order to get control of their land.
The area in which the Yanomami live is rich in minerals, especially
gold. During the 1970s and 1980s, over 20 percent of the Yanomami
were killed by outsiders. Other threats to their existence come from
ranchers and rubber plantation owners who want the land.

Prospecting for Minerals


How do prospectors find ore that is
buried deep underground? To start,
prospectors study samples of rock that
they find at the surface. They have
learned that certain ore deposits are usu-
ally found with certain types of rocks.
Prospectors also use indirect methods.
One technique is to fly over an area
towing an instrument that measures
the magnetic field of the rocks below.
When a site looks promising, small
drilling rigs are brought in to get sam-
ples from below the surface. This is very An aeromagnetic

the end, only one test in a thousand
leads to the development of a mine.

Developing a Mine
When a site has a large deposit of ore,
it may be chosen for development into
a mine. The process of developing a
mine takes many years. Many difficult
jobs have to be done before the first
minerals can be sold.

History people for a very long time. People began
using metals about 5000 years ago. Copper
was the first, and later came tin. Then, a mixture of copper and
tin, called bronze, was used. All sorts of tools and weapons
were made from bronze because it is a very hard metal.
Historians call the time when bronze was so important
“The Bronze Age”—from about 3000 BCE to 1000 BCE.

NEL
C H A P T E R 1 1 : Non-Renewable Natural Resources 225

Obtaining the Rights to Mine Minerals


The land that the ore is on usually does not belong to the mining com-
pany. The company must get permission from the owners before it can
take the ore out. This is called getting the rights, which means buying
the legal rights to the ore from whoever owns those rights. In some
cases in Canada, First Nations people of the area have those rights.

Figure 11.9
Demonstrators protest against uranium mining in the Sharbot Lake area, which is
located north of Kingston, Ontario. Getting the rights to extract minerals often means
negotiating with First Nations people who live in the area. If these negotiations break
down, protests may follow.

Protecting the Environment


Many countries, including Canada, require mining companies to be
sure that they will not cause severe, long-lasting damage to the envi-
ronment or hurt people before they are allowed to build a mine. This
environmental assessment involves a study of what the mine will
do to the land, the air, the wildlife, and the people of the area. The
mining company must show the effects of the mine on the ecosystem.
The study must show that the mine’s impact on the environment will
be at an acceptable level.

NEL
226 U N I T 3 : Natural Resources

Building the Mine


The mining company must determine the best way to extract the ore
from the ground. One method is underground mining. The mining
company digs a vertical shaft down into or near the ore body.
Horizontal stopes, or tunnels, are built out to the ore face. At the ore
face, the ore is blasted into rubble. Load-haul-dump machines pick
up the broken ore and carry it to an elevator. This method is best
when the ore is found far below the surface.
When the ore is found near the surface, mining companies use
open-pit mining. First, the overburden is removed; this is the rock,
soil, vegetation, and sometimes even a water body such as a creek or
a beaver pond that covers the ore. Then, heavy equipment is used
to dig a deep hole into the ore body. Whole mountains have been
completely removed using this mining method.

companies face a big problem. What should be done with the leftover
material, called tailings? Very often, the valuable minerals make up
only about 2 percent of the ore. This means that mining companies
must dispose of tailings equal to about 98 percent of the original
material from the mine. In open-pit mines, the tailings are some-
times dumped in parts of the pit where the ore has been exhausted.
In other cases, the waste is simply put into pits or piles nearby.
One problem with tailing piles is that they often contain dan-
gerous chemicals and minerals that can be washed out of them.
These poisons make their way into the groundwater and streams of
the area. Careful planning and design of tailing storage facilities are
needed to stop tailings from becoming sources of pollution.

Reclamation
Mining scars Earth’s surface. Many countries require mining compa-
nies to make the area safe and productive once mining has stopped.
It is impossible to return the area to a completely natural state.
However, trees or grasses can be planted on mined areas and over
tailing piles to hide some of the scars. Eventually, the land may be
used for grazing animals or for recreation.

resources may be lost if we overuse them or change the conditions

in which they live. For example, some animals have been hunted
to extinction. Also, we are destroying tropical rainforests, which
contain half of Earth’s plant species. All renewable resources will be
available to us only if we treat them with respect and care.

Animals as Resources
Humans have always hunted wild animals for food. Domestication,
or the taming of wild animals, started as early as 12 000 years ago.
Then, animals could be used for many more purposes. Dogs protected
people and their animals (for example, sheepherding), while sheep,
goats, and cattle served as easily available food sources. Over time,
other animals were tamed for use as pets and beasts of burden (or
work animals). People used the skins of domestic animals to make
clothing and shelter. Many domestic animals had dual purposes.
Cattle provided milk, and they were also used as draft animals to
help people do their work.

Types of Forests
About one-third of the world’s land surface is forested. Since growing
conditions are different around the world, forests are different, too.
Forests belong to two big categories:

• tropical forests
• temperate forests

Temperate Forests
Temperate forests are located north of the tropic of Cancer and south
of the Tropic of Capricorn. These forests grow in climates that are
cooler and less moist than in the tropical regions. They have growing
conditions that vary considerably. These growing conditions produce
the following different types of forests:

• Deciduous forests have trees with broad leaves that fall in the
autumn (including oak, maple, beech, and hickory). Deciduous
forests occur where it is warmer.
• Coniferous forests have trees that keep their needle-shaped
leaves all year round and bear their seeds in cones. These for-
ests grow where it is cooler. Tree species include pine, spruce,
and fir.
• Mixed forests grow between coniferous and deciduous forests.
These forests have trees from both kinds of forests.

The Disappearing Tropical Forest


Tropical forests are being cut down at a rate of about 20 million
hectares per year. This is more than three times the area of Nova
Scotia. In Central America, only 40 percent of the original forests
remain. Other places have lost even more. In the Philippines, up
to 80 percent of the forests are gone. Tropical forests are being cut
down for the following main reasons:

• Loggers want the wood.


• Farmers are clearing land to make homes and livelihoods for
themselves and their families. Figure 12.12

The Forest Industries


Since there is so much variety in the forests of the world, there is
also variety in the industries that use them, but the main ones are
logging (using the trunks of the trees), and pulp and paper (using
the wood fibres).

The types of wood products made from logs depend on the types
of trees that are being cut. Deciduous trees found in warmer temperate
locations are hardwoods. This wood is dense and hard. It is useful
for making furniture and flooring. Needle-leafed coniferous trees that
grow in cooler climates are softwoods. Their wood is not as strong as
hardwoods, but the trees grow faster. Canada produces 20 percent of
the world’s total softwood. Most of it comes from British Columbia.

The Logging Process


The following process is used to harvest trees for logs:

• The best trees are marked.


• Loggers come in and cut down the marked trees.
• Branches are cut off the fallen trees.
• The trunks are “bucked”— cut into smaller lengths.
• The logs are hauled to a loading area using heavy equipment
like bulldozers or winches.
• The logs are hauled to a lumber and pulp and paper mill by
trucks, or are floated there down the river.

Many early Canadian folk songs tell


Music stories of loggers in the woods of this land.
The loggers spent the winter in the bush cutting
trees and dragging them to rivers. In the spring, the
flooding waters carried the logs to mills farther downstream. Trouble
occurred when logs jammed up. Loggers would have to go out
onto the jam and attempt to free enough logs so that the jam Selective Logging
would break up. Look up some songs in the music library or
order some music videos (for example, “Log Driver’s Waltz”)
from the National Film Board.

Saving Forests by Cutting Responsibly Strip Logging


Selective logging means cutting down only the mature trees in
a forest. Younger trees are left uncut. With this approach, only
about 20 trees of the 400 in a hectare of forest would be taken
down. However, the cutting and transporting of logs can damage
almost half of the trees in the forest.
Most companies do not use selective logging because they
say it is too expensive. They argue that it takes too much time to Clear-Cut Logging
locate and reach each mature tree.

Saving Resources by Reducing Wastes


The logging industry has become concerned about the amount of
wood they are wasting. Most of the waste occurs in wood debris left
in the forest. Some steps have been taken to reduce waste created by
logging. For example, edges and ends of logs that were thrown away
in the past are now being used to make new products, like chipboard
and particleboard. Even the sawdust shavings and bark that were
once thought of as garbage are now burned to run the logging mills,
or processed into useful items like pet bedding.

Technological Change
New technologies have changed paper making in the following ways:

• Researchers have discovered new ways to make paper that


use fewer chemicals and bleaches. (Bleach is used to make the
paper white.) This means that fewer chemicals are released into
the environment.
• The harmful substances that the industry does use are being
treated more carefully. The industry has reduced its waste
output by 34 percent over a 15-year period.
• Less water is used to make pulp. In fact, water usage is down
by over 50 percent over the past 20 years. This reduces the risk
of overusing waterways that are important wildlife habitats.
• Recycled paper now makes up 26 percent of the fibre in paper
making. Leftover materials from sawmills make up 56 percent
of the fibre.
• Mills have reduced energy consumption by 10 percent in the
past decade.

The breezes that cool you, the Sun that warms you, and the moving
water that refreshes you are all natural resources. These are called flow
resources because they do not remain in one location. Flow resources
move about because of natural actions in the physical environment.
Humans use flow resources in a variety of ways. In fact, we refer
to flow resources as the global commons. These are resources that are
available to everyone. This chapter looks at how we use just one flow
resource — water.

Winds Earth’s surface is hotter near the equator and colder near
the poles. This creates areas of high air pressure at the poles
and low air pressure at the equator. Winds blow from areas
of high pressure to areas of low pressure.

16 percent — the irrigated land — produces about 40 percent of all
the world’s crops. There are three main types of irrigation: surface,
Surface irrigation
sprinkler, and drip.

Surface Irrigation
Most places where irrigation is practised use surface irriga-
tion. In fact, about 96 percent of all irrigation is surface
irrigation. Pipes, canals, and ditches carry water to the fields.
Farmers make small openings in the walls of the pipes to
let the water flow into the canals and ditches and onto the
fields. When the soil is wet, the openings are closed. Some of
the water evaporates when this method is used.

Sprinkler Irrigation
With sprinkler irrigation, the water is carried by pipes to the
field. Then, the water is sprayed onto the crops using a sprin-
kler head, much like how lawns are watered. This system is
used mainly by North American farmers.

Drip Irrigation
In drip irrigation, water pipes run to each plant. Water drips
directly onto the roots. Very little water is wasted with drip
irrigation. Because of the high costs
involved — the cost of labour, the
pipes used, and the high level of
technology needed — this system is
used only in rich countries.

River Diversions
Often, farmers in a region want a lot more water than what they have
to set up irrigation processes. To get the extra water for these farmers,
governments will actually move rivers. The direction and course of a
river are changed. These changes are called river diversions.

Positive Results of River Diversions


Irrigated crops need a great deal of water. Dams and canals are built to
move water to irrigated fields. Today, about 38 000 dams divert rivers
into thousands of kilometres of canals. The central valleys of California
are productive agricultural lands because of canals and ditches filled by Figure 13.11

Why do you think this canal
was necessary?
Problems Caused by River Diversions
River diversions have many serious harmful
effects on the physical environment. Diver-
sions cause huge areas to lose their water.
These areas face water shortages. The number
of plants and animals in the region will
decrease and some species may die off. People’s
livelihoods are destroyed.
Those places that receive the water face a
new challenge — salt. The water carries minerals
that soak into the irrigated soil. When the water
evaporates, the minerals are left behind. Over
time, these minerals form large deposits of salt.
These deposits are harmful to plants and ruin
the soil over time.

The Aral Sea Disaster


The Aral Sea was once the third largest lake
in the world. Only the Caspian Sea and Lake
Superior were larger. However, this lake has
shrunk in area by 50 percent in the past
30 years. Its surface is now 20 metres
below what it was in 1960. Why did
this happen? Much of the water from
the two rivers that feed the lake was
diverted to irrigate cotton crops.
The result was an environmental
disaster. The little water that continued
to flow into the lake quickly began to
evaporate. Minerals were left behind.

Using Water for Hydro-Electric Power


Electrical power is generated by water flowing from a reservoir — often
created by a dam — down a penstock (a chute). The rushing, falling
water pushes on the blades of a turbine and causes them to spin.
A generator connected to the turbine spins as well and produces an
electrical current.
Many rivers around the world are used to generate hydro-electric
power. Globally, about 2 percent of all energy is obtained in this way.
Canada has developed its hydro-electric power because we have so
many powerful rivers. In Canada, we produce about 15 percent of the
world’s hydro-electricity.

Positive Effects of Hydro-Electric Power


Producing hydro-electricity has the following advantages:

• It does not use up any non-renewable fossil fuels.


• It is produced from a flow resource — running water.
• It does not produce greenhouse gases as burning fossil
fuels does.

Used wisely, hydro-electric power is a source of energy that could


continue indefinitely. It is a clean, sustainable energy source.

History planned for places that are far from cities.
These remote areas are often lands belonging to
First Nations. Near the end of the 1990s, in northern
Québec, the Innu tried to stop an expansion of the Churchill Falls power
project. They argued that the construction would destroy their way of life.
The reservoir would flood their hunting areas and destroy ancestral lands.
The Innu had the following to say about the project:
“Go home! Go home! Let the Innu live!”
“I feel as if it’s my own heart that’s going to be flooded.”
“We demand respect for our territory, our way of life, and our rights.”
The Innu protests, along with other problems, stopped the
expansion project. There still are many who would like to see the
Churchill Falls power project create more wealth for Canadians.

together make salt — sodium and chlorine — are not
used up in these ways. They remain in the ocean
water. When the Sun evaporates water, the salt
is left behind. Gradually, the oceans have
become salty from these minerals.

The Distribution of Life in the Oceans


The life that exists in the oceans is very important to people. Most
of the life forms live in the top 80 metres of water. Sunlight can
reach down this far, so plants are able to grow. These plants are
food for fish.
Below 80 metres, there is little light, little plant growth, and few
species of fish. Only in recent years have scientists learned a little
about the types of species that are able to thrive in such low light
conditions. We have much to learn about ocean ecosystems.

Underwater Food Pyramid


Some of the most important life forms in the oceans are also some
of the smallest. Phytoplankton are so tiny that a glass of sea water
would contain millions. Yet, these plants can take minerals out of the
water and grow and live. Zooplankton are microscopic animals that
eat the phytoplankton. In turn, they are eaten by larger animals such Figure 13.24

The Continental Shelves


The shallow areas of the oceans near the coasts of the continents — the
continental shelves — provide about 84 percent of the world’s catch
of fish. New technologies, such as fish finders and larger nets, have
produced greater catches. In some developing countries, the fish
catch is so important that the people get 40 percent of their animal
protein from fish.
However, these areas are vulnerable to threats. Global warming
will have a serious impact on the species of phytoplankton that grow
on the continental shelves. A small change in this basic food source
for marine life will cause enormous changes in all other species.

Inuit and Whale Hunting


Whales were a traditional source of food for Inuit of Canada’s Arctic.
However, over-hunting of whales put them on the endangered spe-
cies list. Most countries of the world banned whaling. In July 1998,
Inuit hunters decided to celebrate the creation of the new territory
of Nunavut by hunting a bowhead whale.

We know little about the oceans’ ecosystems because they are so
complicated. The oceans provide a huge variety of species and con-
ditions. The world’s oceans are so vast that most people believed we
could never affect them. They were very wrong!

Overfishing
With our modern technology, we have become so efficient at catching
fish that we are overfishing the oceans. Some fish species are disap-
pearing. The United Nations has estimated that the most that can be
fished from the oceans is 80 million tonnes of fish per year. If more
than this is harvested, the fish cannot reproduce quickly enough.
They will disappear. We are currently harvesting about 101 million
tonnes of fish a year, which is well over the limit. If this overfishing
continues, fish catches will drop in the future. More people around
the world will go hungry as a direct result.
Canada is already suffering the effects of overfishing. In the
1990s, the amount of cod being fished on the East Coast of Canada
dropped. The government of Canada banned fishing for cod in 1992
because so few fish were left. It was hoped that the ban would allow
the fish to become plentiful again, but that has not happened. Only
a very few cod can now be caught each year. A similar situation is
developing with the salmon stocks on the West Coast.

Pollution
Pollution is another threat to the oceans. Pollution reaches the ocean
waters in the following ways:

• through rivers
• from the atmosphere
• from factories and cities along the coasts
• directly from ships

Oil spills from damaged ships pollute the water. Ships often just dump
their sewage and waste oil directly into the ocean. Those parts of the
world with large populations, such as the coasts of Europe and Asia,
are heavily polluted. People and pollution seem to go hand in hand.

D isaster! Your plane has crashed. You and two friends are stranded
on a small island. There is no hope of being rescued. However,
you can survive. There is food — nuts, berries, and fish in the sea.
A small stream provides drinking water.
You survive for a few months, but then you begin to think of
ways to use the island’s resources to improve your life. You
discuss your plans with your friends. “Why don’t we cut
down more trees and build a really nice hut? Why not
eat more fish? They’re there just for the taking.”
C H A P T E R 1 4 : Sustainable Development 287

Your friends point out some problems. If you cut down the trees
to build a hut, you will destroy the plants that provide your nuts and
berries. Also, catching too many fish today means that there will be
fewer fish to catch tomorrow. The improvements that you want to
make are going to use up your resources now so you will not have
them in the future.
This is the same dilemma facing the people of the world. How
can we use our resources wisely without using up or polluting our
resources? We need to use resources today in such a way that they
are still available for our grandchildren and their grandchildren. That
is what sustainable development is — looking after our resources
without using them up.

Attitudes toward Resources


We must use natural resources to satisfy our needs for food, shelter,
and clothing. However, we usually want more than we really need.
We also seek comfort, entertainment, luxury, and other non-essential
things. Resources for these non-essential wants must be taken from
the environment, too. Unfortunately, we often want more than the
environment can provide in a sustainable way.

What Can You Do?


You are a leader in the fight to save natural resources and the environ-
ment. You are a consumer. You are important. Let us look at some
actions you can take.

Practise the 3 Rs
Reduce, reuse, recycle. The
most important of the 3 Rs
is “reduce.” This will save
resources that are used to
make products and the pack-
aging that goes with them.
For example, you might
share books and magazines
with a friend rather than
each buying the same ones.

Reducing consumption is the first
step to a sustainable society.
What other products could you
buy used instead of new? Can

reduce unnecessary consumption?

NEL
C H A P T E R 1 4 : Sustainable Development 297

Travel Wisely
Use a bicycle or public transit whenever possible. By not using auto-
mobiles, you are saving energy and reducing pollution. At the very
least, commuters should use a car pool so only one vehicle is being
used instead of several.

Figure 14.13
Using public transit like streetcars in
Toronto, Ontario, saves energy and
money, too. How often do you take
the bus or subway? How often do
you and your family bike or carpool?

Figure 14.14
Composting turns waste food
into good soil. Does your
household compost?

Do Not Throw It Out


Compost your organic waste. Putting vegetable peelings,
apple cores, banana skins, and other waste in a composter is
not a big job. The wastes turn into valuable soil, and the land-
fill sites are not filled up. People who live in apartments can
compost by using red wriggler worms. They are safe, clean,
and fun to watch.

Turn It Off
Help to save energy at home. We waste energy at home in
the following ways:

• setting the heating thermo-


stat too high and the air
conditioner too low
• leaving lights on
• keeping windows and doors
open during the heating or
air-conditioning seasons
• letting hot-water taps drip Figure 14.15
