Speed Reading The rainforest is not the only place where animals are How Can We Save Endangered Species? In the modern world, many animals die from causes that are not natural. the species living in the rainforest. Every day, more and more areas of rainfore are cut down or burned, and all of the animals living there lose their habitat. and dying. Around cities, animals are facing similar situations. As cities humans move into the natural areas surrounding them. This means that animal living near humans must move to other areas. Those animals-or in some cases those species-which are not able to adapt or to find new homes eventually die. In recent years, efforts have been made to protect certain lands in order to prevent killing plant and animal species native to the area. State and national parks along with special areas for birds and wildlife, have been established to protect the natural homes of endangered species. Also, wildlife management programs have helped bring back some species from almost certain extinction. For example, fewer than 50 years ago, the North American bald eagle was in serious danger of extinction because too many farmers used DDT, a chemical that kills insects. Farmers stopped 10P 15 >> using DDT, and the bald eagle is no longer endangered today.m Although protected lands have been established and wildlife management programs keep an eye on highly endangered species, scientists have yet to determine if these efforts are enough. Is it possible to save all the plants and animals that are endangered today, or is it already too late?
