Answer
Water use and pollution are problems in many towns and cities. What can we do to solve these problems?
One solution is to reduce the amount of chemicals we put down the sink. In particular we can use environmentally-friendly cleaning products. By doing this, rivers and seas will be less polluted.
Another solution is to save and reuse water at home and at work. For example, we can turn off taps when we are not using them and reuse bathwater in the garden. If we do this, we can reduce the amount of dirty water that ends up in the seas and rivers.
All in all, there are a number of things we can do. If we reduce the amount of chemicals we put down the sink and we save and reuse water at home and at work then we can reduce water use and pollution.
