Baby animals are endangered for many of the same reasons as adult animals, but not always. Some animals, such as pandas, have only one baby, so not enough babies are born to replace the adult animals that die. Cheetah babies are eaten by lions when their mothers leave them to hunt for food. Many polar bear cubs are starving because the ice in the Arctic is melting, and their mothers cannot find enough food for them on land.
