More than one in four species on Earth now faces extinction, and that will rise to 50% by the end of the century unless urgent action is taken. Scientists have labelled the biodiversity crisis as worse than the threat from climate change Over 37,000 species are directly threatened with extinction. That is 28 % of all species assessed.

What is the difference between Extinct and Endangered species?

Species assessed as Critically Endangered (CR), Endangered (EN), or Vulnerable (VU) are referred to as "threatened" species. However, Extinct in the Wild (EW) species can move into the threatened categories following successful reintroduction. Therefore, EW species should be included when reporting proportions of threatened species.
