Released today, the latest update of the IUCN Red List of Threatened Species shows that a staggering 19,265 species are currently threatened with extinction. Over 900 new species have been classified as threatened – that is, considered to be Critically Endangered, Endangered or Vulnerable – since the last update in 2010, showing that there is no let up in the extinction crisis threatening the world’s biodiversity. Although more species are thought to be threatened than ever before, the IUCN are keen to highlight that there have also been major conservation success stories.
