8.1 INTRODUCTION
The Philippines is prone to natural disasters, particularly typhoons, floods,
landslides, volcanic eruptions, earthquakes and tsunamis, lying as it does astride the
typhoon belt, in the active volcanic region known as “Pacific ring of fire”, and in the
geologically unstable region between the Pacific and Eurasian tectonic plates
(Library of Congress, 2006).
Base on the R.A. 9512 of 2008 or an act promoting environmental awareness
through environmental education and for other purposes, environmental education
should be integrated by the schools and different agencies of the government in its
school curricula at all levels, whether public or private, including in barangay daycare,
preschool, non-formal, technical vocational, professional level, indigenous learning
and out-of-school youth courses or programs. This shall include environmental
concepts and principles, understanding environmental laws, the state of international
and local environment, local environmental best practices, the overcome concept to
threats of environmental degradation and its impact on human well-being, the
responsibility of the citizenry to the environment in the context of sustainable
development (Philippine Official Gazette, 2008).
8.2 MOST TOXIC PLACES IN THE WORLD
Human lives have been made easier and more exciting through Science and
Technology but the evidence of waste points to him as the culprit. It made all kinds of
pollutants, which continues to paint an ugly picture of what it has done and perhaps,
will continue to do so because of his undisciplined manner of treating his
environment. Because of the acceptance and patronage of the products of S & T, it 6
was and still able to make a list of places which are detrimental to humanity (Doria et
al., 2018).
Arbogbloshie in Accra, Ghana, was the top on the list of most toxic places on
Earth. It is a giant “waste bin” that is the second-largest e-waste processing area in
West Africa. Ghana imports pre-owned electronics, which are then stripped down of
still usable parts, cleaned them and shipped back to the country of origin. They either
burned sheathed cables to recover copper, lead, etc. the burnt plastics produced
toxic smoke (Toronto Star Newspapers, 2013).

8.3 ALTERNATIVE ENERGY SOURCES
All those things that do not consume fossil fuel are alternative energy and
these are widely available and environment friendly. It causes little or if not almost no
pollution. To reduce our dependence on traditional fossil fuels, there are several
alternative energy projects running in various countries. There are many impressive
choices that man can take into consideration such as solar tankless water heater.
The following are the renewable energy resources according to Shin (2018):
www.youmatter.world
Figure 8.3 Solar Energy
The first energy source in the world is solar. It was in use much earlier before
humans ever learn how to light a fire. Many organisms are dependent on solar
energy from plants, aquatic life and the animals. The solar is mostly used in
generating light and heat. This was widely used across the globe as an alternative
energy source.

Discussion
The second energy source that has been used very long time and for
centuries is the wind energy. It is free of charge and widely available. A single
windmill can power the crop irrigation, and family energy needs, water pumping and
electric lights. The province of Ilocos is widely known for this. And now, a part of
Rizal province has also few windmills.

Figure 8.5 Geothermal Energy in Bicol
Geothermal energy means energy drawn or harnessed from beneath the
earth. “Geo” means Earth and “thermal” means energy. It is completely clean and
renewable. It has been used since last several years. The Philippines is a
volcano-rich country where geothermal heat comes from. Heat is continuously
produced from there. The province of Albay in general and Tiwi tap geothermal
energy to augment the electricity consumption of the area.

Discussion
Hydroelectric power plants capture the kinetic energy of moving water and
give mechanical energy to turbines. The moving turbines then convert mechanical
energy into electrical energy through generators. Dams have been built for this
purpose. It is the largest producer of alternative energy in the world. However, it
could only be beneficial if there is enough water to run the turbines.

Figure 8.7 Sources of Biomass Energy
The process of conversion of biological materials and wastes into energy
sources for heating, power generation and transportation is biomass energy. These
carbon-based substances or materials converted over a long period of time to fossil
fuels are not regarded as biomass. However, in their original state they are regarded
as biomass. This is because of the separation of the carbon they previously
contained from the carbon cycle 10

Figure 8.8 Ocean Energy
Page #
Discussion
The waves produced by the ocean and tides that hit the sea shore has
enormous potential in them. If they harnessed with full capacity they can go a long
way in reducing world’s energy problems. Ocean energy can be tidal energy, wave
energy and ocean thermal energy conversion (OTEC) via which ocean energy can
be harnessed.
Hydrogen has tremendous potential because it is the most abundant and
lighest element available on Earth and can be used to power up homes, vehicles and
even space rockets. But it is rarely alone, it is usually available with other elements
and have to be separated before it can be used. It takes a lot of energy to separate
hydrogen from other elements and therefore it proves to quite expensive to extract it.
There are alternative energy resources which man can harness to satisfy his
power needs. However, we should seek other energy resources if ever we found
even just one alternative energy resources.
8.4 CURRENT ENVIRONMENTAL ISSUES/PROBLEMS
A. Plastic bags. Plastic bags are being banned worldwide and reusable bags are
encouraged to use because of the following reasons according to Green Tumble
(2019):
a) Plastic bags are made up of petroleum, a nonrenewable resource. They are
not biodegradable, instead they breakdown into microplastics that leach
toxicants that pollute the earth and enter our food supply.
b)These are very light weight, the wind carries them across the landscape,
clogging waterways, cluttering our oceans, damaging agricultural lands and
provide ideal breeding grounds for mosquitoes.

c) Animals mistake plastic bags for food, which leads to massive poisoning, choking,
entanglement and blocked intestines that causes to death.

B. Decline of Natural Resources and Biodiversity.
Philippines is suffering from degradation of the natural environment. It has fifty
major rivers now polluted due to abuse and neglect. Approximately two-thirds of the
country’s original mangroves have been lost (Ocampo, 2008).

2000, it had less than 600,000 ha of old-growth forest left.

C. Marine Environment
Marine and coastal resources –including coral reefs, mangrove forests and
seagrasses- are also being degraded and depleted by the impact of climate change,
overexploitation and pollution. Meanwhile, demands on marine resources are
increasing as populations and incomes rise (Water Environment Partnership in Asia,
2003).

Figure 8.14 Pollution that affects the marine environment
D. Air Pollution
Some 54% of the Philippine population uses solid fuel (charcoal, firewood) for
cooking, affecting over 47 million people with indoor air pollution. Indoor air pollution
is one of the main drivers behind acute respiratory infections in children and women 14
(Asian Development Bank, 2018).

E. Water Contamination
Urban and rural water contamination and industrial and household pollution,
including fecal and chemical presence in water bodies, can affect human health.
Water pollution in the Philippines is largely caused by inadequately treated domestic
wastewater and sewage, agricultural wastewater and industrial wastewater.
