Water is one of the basic necessities of life. Clean and pure drinking water can get spoilt because of pollution. Water percolates through the ground. Water bodies rivers become the source of drinking water. Man pollutes water by letting waste into rivers, lake, oceans and wells. Smoke contains gases sulphur dioxide and oxides of nitrogen. These combine with rain water to form acid rain. Acid rain contains sulpuric and nitric acids.
The pollution of water is an important problem today. Today, throughout moutain to city, almost rivers are not pure. They are dark, black, and foul and make the bad trouble with our lives. We need fresh air, we need fresh water. We need water to drink, to bath, to clean and wash. We very need water. Land Dad, and water Mom. Water smooth, transparent, clear, and it has 70% of all our body. We can not don't need water. Water help tree grow. Water can refresh and clear all things. But today, we only have water from water city company. The water we drink, is not fresh. And it must fire to hot as 100 degree. And then, we make it cool, so we can drink. In once upon a time, all rivers are fresh. And we can swim in that, it's very funny. In that rivers, we have fishes, too, and shrimp, and very much see animals. But now, with our rivers, there have no fish, or shrimp. Because there're too dirty. If we want to make our rivers revival, we need learn the way to not pour the pollution things to our rivers. It's very difficult, I know. But if we truely want our rivers have the blue, not black, or grown color, we need do all things from the begin. Nowadays, we have many polluted company, we always try to make pure water. And to have pure water, we must pay money. It's not cheap. And the last thing I want to talk with you, that we need to learn the way to not pour the dirty things to rivers. And we need save our water.
