An environmental group is planning to organize an activity to protect the environment. What activity would you suggest?
I think the most significant activity the environmental group should do is to plant more trees worldwide. It is reported that the desert has occupied a fourth of the earth landing surface. And this process is increasing at a alarming speed. As we know, planting tree can reduce the erosion to green area by wind and soil from the deserts. Because the root of green trees can strengthen the sand in the deserts. By doing this, we can protect the environmental conditions both in the cities and deserts.
