In my opinion water is life and without water there is no life because 70% fo our body is made up of water. A clean and healthy water can help us to maintain healthy life because with healthy water we can work better, think better, our muscles can perform better and our immune system become stronger and perform better with healthy and clean water.

Clean water is very important to a person,because he can't live for a long time. If we don't have clean it can caused o lot of new illnesses
