What is rain? Rain is water from atmospheric water vapor. It has many advantages for the earth and people, because they need it. Why the rain is important for the earth and people?
 Many people in Thailand have careers are farmer. Accordingly, water is the main of factors. If the farm they do very far from the river, it very difficult to manage, so if the rain falls, it can help them easy to plant. Meanwhile, the rain has many advantages, for example, increase soil moisture and air, reduce drought, water source, photosynthesis, etc. The main of the reason is they will have tap water to use because rain is freshwater, we use water to drink, take a bath, and wash something everyday. If the rain doesn’t fall, it will make a drought and warping of ecology. That is cause why the rain is very important and why we need it very much. In the present, we have artificial rain, it’s very useful when the rain doesn’t fall, but real rain is better.
 For this reason, we should help maintain our forest for the water Cycle still well. Inasmuch as, the tree built the rain and the rain built the tree.
