Why do you think so? I think water pollution is the most serious problem facing the earth because we need clean drinking eater to survive and because animals and plants must have clean water, too.” If water is polluted. People will not be able to get clean water to drink; therefore, many people will get sick, Its terrible. 2. What causes the problems? I think it is because people pay no attention to our environment. They pour water into rivers, lakes and seas without cleaning it The air pollution is caused by the factories. People build factories to develop the industry, but they never pay attention to controlling the pollution. The harmful smoke should be made harmless before it goes into the air, but few factories would like to d so because this will cost much. 3. What can we do to solve the problem?
