GEOLOGY

Detailed explanation-1: -The reason that logging is so bad for the climate is that when trees are felled they release the carbon they are storing into the atmosphere, where it mingles with greenhouse gases from other sources and contributes to global warming accordingly.

Detailed explanation-2: -Trees and other plants absorb carbon dioxide from the atmosphere as they grow. This is converted into carbon and stored in the plant’s branches, leaves, trunks, roots and in the soil. When forests are cleared or burnt, stored carbon is released into the atmosphere, mainly as carbon dioxide.

Detailed explanation-3: -The degradation of forests ultimately leads to a decrease in oxygen and a sufficient increase of carbon dioxide in the atmosphere. In order to make up for the loss, more trees are being planted. As a result, the amount of carbon dioxide in the atmosphere could significantly decrease.

Detailed explanation-4: -The loss of trees changes the quality of soil which leads to soil erosion, fewer crop production and flooding. The biological cycles (Bio-geo chemical cycles) are altered because of deforestation. The amount of carbon di oxide increases in the earth which leads to global warming.

Detailed explanation-5: -Without carbon dioxide, Earth’s natural greenhouse effect would be too weak to keep the average global surface temperature above freezing. By adding more carbon dioxide to the atmosphere, people are supercharging the natural greenhouse effect, causing global temperature to rise.
