Many animals are at risk of becoming extinct, or no longer part of the animal kingdom. When animals' habitats are destroyed or damaged, they can die because of lack of food and space to live. Forest habitats are very often destroyed because we cut down trees for wood. Some endangered animals are the Sumatran tiger, the ivory-billed woodpecker, the northern white rhinoceros, and the black-footed ferret. There are many ways to help save endangered species such as recycling and not polluting the environment.

Wildlife scientists study animals and plants, and they learn about endangered animals and how to help save them. Many times animals are tagged to study them and track them. Dr. Ian Stirling studies polar bears and retrieves data by observing them throughout the year. Dr. Jane Goodall studied chimpanzees all her life and learned many interesting things about the way they live, which is much like humans. She believes that we can help animals and promote peace in the world.
