People have cut down forests to clear land for crops, cattle, roads, and cities. These trees are also used for fuel, building material, and paper. The loss of forests have had the following effects (choose all that apply):
A. Causes many species to lose their habitats and food sources, resulting in many becoming extinct or endangered.
B. Creates erosion. The roots of plants hold soil in place to prevent erosion and absorb rainwater, preventing flooding.
C. Creates pollution with the use of DDT, which is a fertilizer that impacts the health of many organisms in the area.
D. Contributes to global warming. The abundant plant life in forests takes in carbon dioxide and stores the carbon as a source of energy. Without forests, the carbon that would have been stored in the trees exists as carbon dioxide and contributes to global warming.
