HOW IS THE CLIMATE OF AN AREA AFFECTED BY DEFORESTATION AND THE RESULTING AGRICULTURAL OR URBAN LAND USE?

Deforestation is clearing rain-forests and woodlands to put in buildings and cities and houses. Rain-forests will soon be gone if we continue to cut down rain-forests and woodlands.

The cleared land is only good for a few years before the nutrients in that area are all used. Then you can no longer grow crops on that land. That piece of land is then deserted and abandoned. After that, the land is left for waste. More land is needed to grow crops.

Deforestation also affects the water and carbon cycle. When the trees are cut down the trees can’t give off mist to create rain clouds. When that happens then there is no rain and the land gets dryer and dryer. It affects the carbon cycle, when the trees are burned down carbon dioxide is released into the atmosphere. The carbon dioxide increases green house effect which makes temperature increase which can cause global warming.

When plants and trees are cleared it reduces the tree canopy that makes the air cool. That makes less rain because water does not evaporate form the forest. This makes the land dry and affects the water cycle. Less water makes less rain.

HOW IS THE GLOBAL ECOSYSTEM AFFECTED BY DEFORESTATION AND THE RESULTING AGRICULTURAL OR URBAN LAND USE?

Animal and plants that live in a rain forest can become extinct certain animals only live in small areas of the forest. When the forest is cut down there is nowhere for these animals to live. Forest destruction makes the soil erode. This makes silt and sediment go into the water. The sediment and silt clog creeks and rivers. This changes or stops water flow. Some land can be flooded. Animals and plants can be lost. Nitrogen also gets into the water which makes the acid levels go up. More acid in the water affects plants and animals.

Cities can affect a ecosystems. During the day concrete reflects heat back into space. During the night asphalt releases heat. Average temperatures in cities have gone up. This head affects weather patterns.

WHAT OTHER SIDE AFFECTS CAN BE RESERVED AS A RESULT OF DEFROESTATION?

· Human over population · Catastrophic loss from natural disasters. · Loss of medicines found in rain-forests · Loss of culture · Loss of gene pools · Loss of recreational areas
