A crash course in changing the world.
Water is very important, but many company, factory and people make the river dirty. I think many people don't know how important the water is. I want the water get cleaner than now.First I need to learn about the water and how to clean water because I need the knowledge about water. Second I tell to people how important the water is and teach how to clean it. After people understand those, we pick up the trash in the river. Picking up the trash is very important. It can know that we throw away the trash very much and we made mistakes to the water. Also it can learn about the water. Third we clean the river. We do the technique that I say to people. It takes long time, but we can do it fast if their teamwork are good. And finally, the river may be clean. I want to tell the knowledge and technique that I learn to people. It can be cleaner than now.
