What contributes to flooding

There are lots of things that contribute to floods. Humans are one of them and there are two more reasons which are nature and ecology. Humans contribute to cause flooding because humans cut trees down and trees can prevent flood. Humans also does global warming to make floods happening. Nature contributes to floods by sending heavy rains and because of global warming the icebergs are melting and causes sea level to rise. The ecological factor also contributes to floods because of erosion, deforestation and land conversion from trees to housing areas. So as you can see there are lots of causes of flood and we have to stop doing our contribution to flood. Trees can help to stop flooding because trees can help with two things. The first one is trees can absorb water and the second one is by holding soil with their roots and it also can prevent erosion.
