[In June 2015, a study published by experts from Stanford, Princeton and the University of California-Berkeley declared the world’s vertebrates are going extinct 114 times faster than the natural rate of extinction, according to the Huffington Post.
The researchers write that “these estimates reveal an exceptionally rapid loss of biodiversity over the last few centuries, indicating that a sixth mass extinction is already under way.”
Last year, we published the following list of every animal that went extinct in the last century. Updating it today to highlight the most recent study and news that the U.S. Fish and Wildlife service have declared the eastern cougar extinct. And we’re dangerouslyclose to losing 13 more animal species.
The number of extinct animals is difficult to calculate and always higher than the estimate. In some cases, a species is presumed extinct — none have been seen in years — but it’s yet to receive official extinction status by the IUCN. But the important thing to remember is that extinction is not a historical problem — it’s a contemporary issue.
In the article, take a look at every animal (except insects, which are extremely difficult to catalogue but which you can find here) that went extinct in just the last 100 years. The list is based on research provided by the Sixth Extinction, a website created to “enhance free public access to information about recently extinct species,” and in order of their approximate date of extinction. We’ve included all the animals confirmed extinct by the IUCN, and added a few more declared extinct by other credible individuals and organizations.]
