Visuals: Threat of extinction

Over 900 animal species have gone extinct since the year 1500, and many more are threatened with extinction.

Extinction means that an entire animal species dies. For instance, the Dodo bird, a flightless bird that used to live on the island of Mauritius, went extinct in the 18th century because of overhunting by humans.
