Endangered species
An endangered species is a group of animals that could soon become extinct. ______16______ Many species are nearly extinct and could disappear off the face of the earth very soon if we don’t do anything to save them. There are many reasons why species become endangered.
Habitat destruction is the main reason why animals become endangered and this happens in two ways. When humans move into a new area, the animals’ habitat is destroyed and there is nowhere for them to live and nothing to eat because humans chop down trees and build houses and farms. ______17______ Chemicals in rivers and poisons on farms cause the destruction of animals’ homes and food supplies.
_________18_________ Animals have been brought to the edge of extinction because they are killed for their highly-valued meat, fur, bones or skin, or just for sport. Overfishing has resulted in many large sea creatures like whales and sharks becoming endangered species.
________19________ We should take care not to pollute natural areas, and farmers or companies who destroy animal habitats should face severe financial penalties. The public can help out by refusing to buy any products made from these animals’ body parts. Governments can help, too, by making it against the law to hunt, fish or trade in endangered species. They can also provide funding for animal sanctuaries, to protect animals from extinction by breeding more endangered animals, which they later release into the wild. ______20______
A. Animal habitats are also destroyed because of pollution.
B. Endangered species are also the result of hunting and fishing.
C. Eventually, all the creatures on Earth will enjoy being together.

G. If we all cooperate and take these steps, we will protect these animals for future generations.
