A list of mammals that are facing immediate extinction or have already gone extinct. Some of these extinct animals
have disappeared directly due to humans, often as a result of over-hunting, but changes in habitats and climates, as well as other natural factors, have also contributed. In November of 2011, it was announced that the last wild Western Black Rhino specimens had died out, thus indicating that it was the latest mammal species to go extinct. Other rhino species - such as the Javan Rhino, the White Rhino of Central Africa and the Northern White Rhino - are also under the immediate threat of extinction.
It is estimated that about 25% of the mammals currently alive on Earth are at some risk of extinction, despite the efforts of environmental and conservation agencies worldwide. The largest causes remain the loss of habitat - in large part due to man-made pollution or the expansion of human civilization - though poaching remains a prevalent issue in much of the world.
This list is not entirely complete, as it's unknown exactly what the status is for many mammalian species. But it does attempt to collect, in one place, known mammal species that have become extinct.
