On a bright sunny day, it's been a long time. The hot weather made the weather very uncomfortable, and the water was exhausted. People did not have water to drink, crops died because they were not irrigated. The animals also died gradually. The only source of water is from subsidies from another country. But it couldn't be enough to satisfy the people. If there is a drought, life will become like that, so we have to save water. No matter how much fresh water you use, it will end up using it, so we have to think about how to make it. But first, we must first consciously save water.
