Logging of the temperate forests is a major threat to the biome and everything thereby inclusive. In North America loggers have devastated many temperate forests. For instance, of the ninety-five percent of forest covering the state of Ohio in 1800, only fifteen percent remains. deforestation not only affects the trees, but it also affects every plant and animal living in the area. Because of deforestation, the Carolina parakeet became extinct in the early 1900's. Other animals, like the Mississippi sandhill crane, bears, woodland caribou, goshawks, wolves, fox, and mountain lions, are also becoming endangered .
Logging also ruins the soil. When trees that hold the soil together are cut down, the soil can easily be eroded. The ground under the soil is a mixture of clay and rock, which most plants cannot grow in.
Also, logging pollutes the water and the air. As soil is washed away by water, it usually ends up in fast, clear water streams. The excess soil slows up streams and threatens fish species.
Air is polluted when the trees are cut down. Trees act as natural filters of pollutants from cities and factories. These pollutants end up on the leaves of the tree and are eventually brought back down to the soil. When trees once filtering air pollutants are cut down, the pollutants remain in the air. These pollutants, especially those that are released from burning petroleum products, can mix with water vapor and form acid rain. Acid rain can destroy a forest by killing some types of trees and leeching nutrients from rich soil.
