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. When poachers kill elephants and rhinos, the calves are often left behind to die. Baby orangutans are captured as pets, and many die during transport. Amazing pictures of baby animals will make students feel more motivated to learn about endangered animals and how to help them.
