One of the most urgent environmental problems in the world today is the shortage ofclean water. Having clean drinking water is basic human right. But acid rain, industrialpollution and garbage have made many sources of water undrinkable. Lakes, reservoirs andeven entire seas have become vast pools of poison. Lake Baikal in Russia is one of the largestlakes in the world. It contains a rich variety of animals and plants, including 1,300 rarespecies that do not exist anywhere else in the world. But they are being destroyed by themassive volumes of industrial effluent which pours into the lake everyday. Even where lawexisted, the government did not have the power to enforce them. Most industries simplyignore the regulations. The Mediterranean Sea occupies 1% of the world’s water surface. Butit is the dumping ground for 50% of all marine pollution. Almost 16 countries regularlythrow industrial wastes a few miles off shore.Water is free to everyone. A few years ago people thought that the supply of clean water inthe world was limitless. Today, many water supplies have been ruined by pollution andsewage. Clean water is now scarce, and we are at last beginning to respect this precioussource. We should do something now.
