Function of My Tree

   In our environment, more and more area are drought. So , human need more trees to keep the H2O. My tree has a lot of function, such as, photosynthesis, respiration. In my opinion , the most important function is my trss can fix the water. As everyone knows that  lack of fresh water is threatening the survival of human beings, animals and plants on the globe. My tree can take advantage of respiration in soil and water conservation.
