Spring is the best season of a year. The weather gets warmer and warmer. My classmates and I took a one-day sightseeing tour around our city. The scene was very beautiful. But when we saw the rivers along our city, I felt very sorry and thought a lot.

With the development of modern industry and agriculture, more and more waste is being poured into rivers. It has caused serious pollution. The rivers are becoming so dirty that nothing can live in them. The rivers are giving off a terrible smell.

We make an urgent appeal that measures should be taken to cope with the situation. Our government should build various facilities such as sewage treatment plant and encourage scientists to work out more and better ways to reduce water pollution.

Water is the source of our lives. It is very important to protect the water.
