More than 35,000 species have been evaluated to be threatened with extinction today. One-quarter of the world’s mammals; 1-in-6 bird species; and 40% of amphibians are threatened. There have been five mass extinction events in Earth’s history: ‘The Big Five’.

Why are more species being listed as being threatened with extinction?

As more species are evaluated, inevitably, more will be listed as being threatened with extinction. This means that tracking the data on the number of species at risk of extinction over time doesn’t necessarily reflect an acceleration of extinction threats; a lot is simply explained by an acceleration of the number of species being evaluated.

Why are aquatic animals in danger of extinction?

At-risk aquatic animal species are in danger of extinction from habitat loss, pollution, disease, over-exploitation, and competition from invasive species. The loss of these species could affect many benefits that we derive from aquatic ecosystems.

Can the fish and Wildlife Service decide that a species is endangered?

A recent ruling from the federal District Court in DC provides an important lesson that the US Fish and Wildlife Service would do well to heed: the agency has limited discretion to find that species are threatened rather than endangered.

How does a species become extinct?

A spe- cies becomes extinct when it no longer exists in the wild or in captivity. An important first step in under- standing why species become threatened or endangered is, therefore, to understand the process of extinction.
