Extinction of a particular animal or plant species occurs when there are no more individuals of that species alive anywhere in the world - the species has died out. This is a natural part of evolution.

But sometimes extinctions happen at a much faster rate than usual. For example, at the end of the Cretaceous period 65 million years ago, a mass extinction caused the death of many different types of animals and plants, including the dinosaurs.

Endangered - Endangered species are those plants and animals that have become so rare they are in danger of becoming extinct. Threatened species are plants and animals that are likely to become endangered within the foreseeable future throughout all or a significant portion of their range.
