Overview
How Species became Endangered
In the United States 735 species of animals and 496 species of plants are threatened or endangered. Animals become endangered by habitat destruction, exotic species coming in, pollution and many more. These endangered species must be saved. If the species die they mess up the ecosystem and don't give generations in the future a chance to see them. As humans we have the responsibility to protect them. We can protect them by supporting and volunteering at national parks and also not polluting.
IUCN Redlist
All over the earth, extinction is happening every day. But all the way back in 1963 some scientists were thinking ahead of everyone else. They decided to create the IUCN Redlist, an organization to reduce extinction. The IUCN Redlist is a comprehensive inventory of biological species. If you visit the website there is many different categories. Each category organizes the animals so that you can find every single animal no matter if its endangered or not.
The different categories on IUCN are:
Extinct - no known individuals on earth
Like a Baji River Javan Tiger
Extinct in the wild - No known individual in the world, known only to survive in captivity or a naturalized population, outside its historic Range.
Like a Sumatra Oryx
Critically Endangered - extremely high risk of extinction in the wild.
Like a Mekong Giant Salmon Carp
Endangered -high risk of extinction in the wild.
Like a Snow Leopard
Vulnerable - High Risk of endangerment in the wild.
Like a lion
Near Threatened - likely to become endangered in the near future.
Like a narwhal
Least Common - lowest risk
Like a giraffe
