Just as you thought a drought was bad just think if there was too much water. Without our trees and plants it is easier for topsoil to collect water, causing water to build up creating a flood. Too much water can cause bad land issues like wind and soil erosion. Deforestation causes erosion by exposing top soil to wind and rain. Without trees and other plants, soil is washed into streams or bodies of water. This is harmful in many ways; first the soil is unable to regenerate and also destroys marine life. Furthermore the land is more open to flooding.By removing trees this will cause an increase in carbon dioxide. It is estimated that more than 1.5 billion tons of carbon dioxide is released into the atmosphere due to deforestation. As the carbon dioxide gathers it produces a layer in the atmosphere that traps radiation from the sun. The radiation converts to heat which causes global warming. This is the greenhouse effect.
