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 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./
