It’s estimated the earth has anywhere from 5.3 million to 1 trillion different species. The International Union for Conservation of Nature discovered just over 31,000 of these species are threatened with extinction. Red wolves are considered critically endangered by the IUCN. They became extinct in the wild in 1980 but were reintroduced 7 years later by the United States Fish and Wildlife Service. Kemp’s Ridley turtles are mainly found along the Gulf of Mexico and considered critically endangered. They’re the smallest species of sea turtle, endangered due to the over-harvesting of their eggs. Florida panthers used to be found across the southeastern region of the US. There are only between 120-130 of them left in the wild. As of 2001, there are less than 50 Columbia Basin pygmy rabbits left in the wild, these being the smallest rabbit species. They used to live across the northwestern region of the US however now they’re limited to Washington State. The Eskimo curlew bird is critically endangered and some scientists speculate that it may already be extinct. The last known sighting of the Eskimo curlew was in 1963. Staghorn coral has experienced a population reduction of over 80% in the last 30 years. They are typically found in tropical reefs with disease and climate change being major threats to their species
