Do trees affect soil?
First of all plants don't affect erosion in fact, they help us to stop soil from eroding. The process of wearing away of soil slowly over a period of time by wind , water , etc. is called soil erosion . The roots of the plants hold the soil and its particles together to prevent the soil from erosion . That's why we must plant trees to stop soil from eroding. =D
The way(not really the best) to prevent soil pollution is to plant more trees because trees help in cleaning soil, maintaining its fertility. Trees are helpful to us because without trees, we'll not have the right soil and soil is the place where things get decomposed(things that can decompose only). That's my simplest answer for that question. posted by: joseph_ck16
