Eis forExtinct

A plant or animal is extinct if there are no more of them alive anywhere in the world. You can only see extinct animals in books, or stuffed in a museum like the dodo in the picture. Today, animals usually become extinct because people cut down all the trees and plants in the area where they live and they have nothing left to eat, or because people introduce a strange new animal that either eats them all so there are none left, or eats all their food and there is nothing left for them to eat.
