Conservationists named 22,413 out of 76,199 species of plants and animals surveyed as at risk for extinction, according to the annual update to the International Union for the Conservation of Nature (IUCN) Red List, released this week. In the past year alone, 33 species have been declared extinct. The update points to pressures from activities like fishing, logging, mining and agriculture as the main drivers for species loss.
The list, which marks its 50th anniversary this year, is considered the world's foremost inventory of the conservation status of species.
"Each update of the IUCN Red List makes us realize that our planet is constantly losing its incredible diversity of life, largely due to our destructive actions to satisfy our growing appetite for resources," says IUCN Director General Julia Marton-Lefèvre.
Here are some of the species who have been named this year:
