Thousands of plants and animal species may be in danger of becoming extinct and disappearing forever. Some endangered species include giant pandas, tigers, and the silver sword plant, which is found only on the Hawaiian islands. Many species are threatened because of human actions. But by creating laws to preserve natural habitats, we may be able to save some of them.
