Ecological and need for Ecological Approach

Ecology is the science of the study of ecosystems. it has been defined by various online dictionaries
as "a state of dynamic equilibrium within a community of organisms in which genetic, species and
ecosystem diversity remain relatively stable, subject to gradual changes through natural
succession." and "A stable balance in the numbers of each species in an ecosystem."

The most important point being that the natural balance in an ecosystem is maintained. This balance may
be disturbed due to the introduction of new species, the sudden death of some species, natural hazards or
man-made causes. In this field trip we will explore how human population and development affects the
ecological balance.

Take time to explore this site as your gateway to the world of . It has interesting articles and facts. There
are features such as the Environmental Timeline that shows how there were different concerns about the
environment throughout history.
The environmental impact of war is an interesting article on how preparation of war and warfare leads to
environmental losses.

The carpet bombing of the lush green forests during the Vietnam war led to the loss of habitat of many
species. Special features on population and the environment show how population has increased from the
industrial age and how it will affect the environment. There are additional resources for higher classes.

In the name of development, we remove trees and vegetation, change how we use land, and keep
expanding paved areas. All these not only affect the soil ecology, but also the water balance. Increased
urbanization also requires more water to feed the city's population and industry, often requiring deeper
and deeper wells to be drilled or water to be moved from even more distant locations.

Increase of pavement area not lonely lessens the amount of water vapour that transpires back from the
vegetation but also contributes to groundwater pollution if the salt used to melt road ice were allowed to
runoff into the natural drainage system. for a detailed look at water as a precious resource and how human
development affects water and its ecosystem. It is dedicated to Water Day.

To understand how human population and increased developmental activities affect the ecosystem, there
are live examples all over the world. Armenia is one such example of what is happening to the ecosystem
because of increased population and developmental activities. Over the last 1,000 years human impacts
on the land have increased, mainly through deforestation and increased use of pastures.

Such problems have intensified over recent years with unprecedented population growth and urbanisation
since 1920, resulting in increased human impacts not only on individual species, but also on whole
ecosystems.  and you will consciously become aware of what unchecked industrial development and
urbanization could do to your region.

The fast pace of development has led to many unwanted results. Exotic species get destroyed faster than
we can discover them and ancient ecosystems are getting disturbed in our scientific explorations. Find out
about amazing facts on human impact on oceans, toxins, and much more as you  for environmental
education on the web.

It is designed primarily for kids, but the features and articles are good reading for any grade. There are
also handy tips on what you can do to help protect the environment and ideas on how you can start an
ecology club in your neighbor hood. Visit the resources given on the Ecology and great Links pages to

Ecological balance is a term used to describe the equilibrium between living organisms such as human being, plants, and animals as well as
their environment. Photosynthesis that takes place in ecosystem contributes to building a good environment that stabilizes the coexistence of
all organisms. Harmonious relationships reflect healthy and desirable ecological balance. Human being plays a key role to maintain
ecological balance because they have the highest thinking capacity as compared to other living organisms. Sufficient food availability to all
living organisms and their stability reflect the existence of ecological balance. Therefore, this balance is very important because it ensures
survival, existence and stability of the environment.
Survival of all organisms is actualized due to ecological balance. Various species survive because favorable ecosystems were created.
Favorable ecosystem ensures that each organism thrive and multiply as expected. They get enough food to keep them alive. Ecological
balance is also important because it leads to the continuous existence of the organisms. It ensures that no particular species is exploited or
overused. For example, human activities such as farming and resources exploitation are checked to prevent excessive destruction of the
forests. Deforestation leads to drought. Drought reduces food production resulting to insufficient food. Insufficient food leads to starvation
and later death occurs, hence reducing the existence of some species.
In addition, ecological balance ensures the stability of the organisms and environment. It creates a conducive environment for organisms
multiplication and thriving. It enhances a stable environment that is free from ecological imbalances such as flood, hunger caused by
drought, windstorm that may wipe out everything and over hunting of the predators. This calls for collective efforts to ensure a stable
environment is created. Human activities influence the environmental stability. Tree planting and reduced deforestation rate prevent
undesirable climate change. Control of excessive wild animals’ inhabitant maintains desired population growth. Therefore, a human can
contribute positively to create and maintain ecological balance.
In summary, the ecological balance brings the existence of the world. Earth’s inhabitants such as human beings, plants, animals and other
micro living organisms continue to survive. These species get the conducive environment to multiply and thrive. The world gets to produce
sufficient food for all species. Hunger caused by drought becomes history. This is because the drought will never be experienced at any point.
Also, green environment is maintained. This means that the world achieves its equilibrium state that benefits and protects all living
organisms in it.
