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.
