Passage 31
Water Pollution
Water is very important to us. Factories and plants need water for industrial uses and large pieces of farmland need it for irrigation. Without water to drink, people die in a short time.
Today most water sources are so dirty that people must purify 1 water before drinking. Water becomes dirty in many ways: industrial pollution is one of them. With the development of industry, plants and factories pour tons of industrial wastes into rivers every day. The rivers have become seriously polluted, and the water is becoming unfit for drinking or irrigation. The same thing has also happened to our seas and oceans. So, the problem of water pollution is almost worldwide.
Scientists of many countries have done a lot of work to stop pollution. The polluted water in some places has become clean and drinkable again. Perhaps one day the people in all towns and cities will be drinking clean water. That day, we believe, is not very far off. (161 words)
