Rainforests are very important for our environment and biosphere.They supply a large number of oxygen that our human beings are taking advantage from it.However,the rainforests are decreasing because there are people who destroy them because they need wood and land.It seems like we can get certain benefits from the wood and land for the time being,but to think about our future generation,it is malicious for our global surrounding.Without large piace of rainforest,the quanlity of soil will oviously get worse,and the area of desert will increase very fast.
Thus,everyone needs to protect them and try to use other material to replace wood.Also,we need to use our land in a scientific way to help our offsprings!
