ENDANGERED SPECIES

The World Conservation Union (IUCN) publishes a revised Red List of endangered and threatened species, creating a world standard for gauging threats to biodiversity. Later versions report that one in four mammal species and one in eight bird species faces a high risk of extinction in the near future.
