There is an international list of all threatened biological species that keeps track of their extinction risks. It is called The International Union for Conservation of Nature’s Red List of Threatened Species (IUCN Red List). Enthusiasts and organisations from many countries help by submiting and assessing the data. There is also another list called the IUCN Green List that keeps track of all the protected areas in the world.
