Review that people can change the environment in positive and negative ways. Ask your child if he knows what endangered species are. Explain that some animals are on an endangered species list, which means that there are very few of that type of animal living on earth. There are also species of animals that cannot be found on earth anymore. These animals are extinct. Once an animal is extinct, it has vanished from the earth and will never return. Laws protect endangered species so that the animals do not become extinct. Changes in the environment caused by humans can contribute to animals being endangered or extinct.
