Endangered Species
No living thing exists in isolation. All are part of a complex, delicately balanced network of ecosystems. The removal of a single species can set off a chain reaction affecting many others. The full significance of extinction is not always readily apparent. Species are going extinct at an alarming rate worldwide, forever weakening the fabric of natural communities and ecosystems. These dramatic declines in species are due primarily to the intensive human use--and abuse--of their habitats. Every animal or plant that disappears makes it less likely the ecosystem it was connected to will continue to function properly.
