An “endangered species” classification helps federal agencies and other organizations protect species that may be at risk of extinction from a given area. A species is usually classified as endangered after its' habitat becomes reduced or fragmented or its population number gets critically low. A "threatened species" is one that is likely to become endangered in the near future.

It is hard to estimate the number of endangered species worldwide, but scientists agree that a mass extinction event is happening worldwide. Some extinction is normal, but we are now losing species at about 100-10,000x the normal, “background” rate. Most of these species are at risk due to human activities, including those driving habitat loss, introduction of exotic and invasive species, and global climate change.
