​More and more species of animals are endangered because of serious pollution, excessive buying and expanding industry'
Endangerment is a complex issue that involves the ecosystems where species live and interact together. Measures are being taken on specific issues of endangerment, but without protecting the environments where endangered species live, these efforts will be in vane.

There are many reasons why a particular animal or plant may be threatened by extinction. Scientist analyze these factors and classify them in groups.  The following are the main factors that lead to endangerment:

Loss of Habitat

Earth is in a constant state of change, causing wildlife habitats to be altered and modified. Natural changes usually occur gradually, causing minimal stress on individual species. Humans have caused changes on our planet to occur at a much more rapid pace, leaving little time for wildlife to adjust to their new circumstances. Rapid habitat loss is the single most primary cause of endangerment. Most of the planet has now been modified by human activity, a trend that continues to accelerate.  The consequences may be disastrous.

Humans are depleting the soils of the earth, eradicating its forest and causing the extinction of fish and various marine animals.  Wild lands are quickly being converted to housing and farmland.  Space once home to plants and animals are being eliminated at an alarming pace.
