Cutting trees reduces vegetation that protect soil from agents of erosion. The roots of trees offer organic matter on which soil particles bind to and hence become less easily carried away by water runoff or wind. Trees also act as good windbreakers hence reducing the speed at which winds can carry oil particles.
Explanation:
A decrease in trees also means increased carbon dioxide in the atmosphere. This is because trees are major carbon sinks because they sequester carbon dioxide from the atmosphere into their tissue through photosynthesis. Trees also evolve oxygen during photosynthesis. This supply of oxygen is important in safeguarding the ozone from degradation. A decrease in ozone would cause an increase in penetration of UV radiation that harms genetic material.
