Water pollution-水源污染
Water is used in homes, in farming, and in manufacturing. The water used by the people comes from oceans, lakes, rivers, and streams. Many water sources are becoming polluted. People are throwing things into the water. Factories are dumping waste materials into the water. Cities are dumping sewage into the water. Some water sources have become so badly polluted that the water cannot be made fit to use. Would you like to drink water that came from a source that had been so badly mistreated? Now is the time that we should take up our responsibility to protect our environment from being polluted.
