Dear editor，

As we all know， no life can live without water． Water is of great importance to all living things． Not only do people need water， but also plants and animals need water．
However， as the population grows and industry and agriculture develop， more and more water is needed and used． Besides， many beautiful rivers and lakes have been polluted by the waste water from factories， and the polluted water even does harm to people as well as other living things．
Therefore， it's high time we took measures to prevent water from being polluted， to save water as much as possible and to protect the water source on the earth． Otherwise， the last drop of water on the earth will be human's tear!
Yours，
Li Hua
