Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
Cutting down forests and clear-cutting large areas of land causes:
A
Contamination of ground water
B
Depletion of aquifers
C
Erosion of soil
D
Death due to poisoning
Explanation: 

Detailed explanation-1: -More immediately, the loss of trees from a forest can leave soil more prone to erosion. This causes the remaining plants to become more vulnerable to fire as the forest shifts from being a closed, moist environment to an open, dry one. While deforestation can be permanent, this is not always the case.

Detailed explanation-2: -Trees tend to bind their roots to the soil bedrock, thereby reinforcing the soil. Additionally, the plant litter generated by trees offers protection to the surface of the soil. In the absence of trees (as a consequence of deforestation), the soil becomes vulnerable to erosion.

Detailed explanation-3: -Soil compaction, low organic matter, loss of soil structure, poor internal drainage, salinisation and soil acidity problems are other serious soil degradation conditions that can accelerate the soil erosion process. This fact sheet looks at the causes and effects of water, wind and tillage erosion on agricultural land.

Detailed explanation-4: -Final Answer: The given statement is True.

Detailed explanation-5: -Deforestation and forest degradation are responsible for around 15% of all greenhouse gas emissions. These greenhouse gas emissions contribute to rising temperatures, changes in patterns of weather and water, and an increased frequency of extreme weather events.
