An endangered species is a group of animals that could soon die out. Many species could disappear very soon if we don't do anything to save them. There are many reasons why species become endangered but most of them are because of humans. However，there are things that we can do to save endangered species.
Habitat （栖息地） destruction is the main reason why animals become endangered. When humans move into a new area，the animals' habitat is destroyed and there is nothing to eat because humans cut down trees and build houses and farms.
Endangered species are also the result of overhunting and overfishing. Some seal species are endangered because they are killed for their fur to make coats. Tigers are shot to make medicine and crocodiles are caught to make bags and shoes. Other animals are killed for their fur，bones or skin，or just for sports. Overfishing means that large sea animals like whales and sharks have all become endangered species，because too many are caught to make things like shark's fin soup.
So what can people and governments do to protect animals and stop species from becoming endangered？We should not pollute natural areas，and the public can help by not buying any products that are made from animals' body parts，such as seal fur coats or crocodile bags. Governments can help，too，by making it against the law to hunt，fish，buy or sell endangered species. They can also provide money for nature reserves and zoos. If we all work together by taking these steps，we will protect our planet so that our children and their children can keep living in harmony with other creatures，too.
