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

Do you think the animals can understand each other? The answer is yes. They can communicate to each other by signs and sounds. For example, dogs communicate in many ways. They not only bark, even they howl, growl, snarl, and whine. They lift a paw, or bare their teeth. Other dogs can understand what these sounds and actions mean_.
Animals communicate with each other not only with sounds and movements but with smell. Most animals that live in herds depend on smell to keep together. And, of course, we know how dogs recognize each other by smell.
Apes are supposed to be among the most intelligent of animals, yet, they really have no better “language” than other animals. They make many sounds and expressions of the mouth to communicate their feelings of anger or hunger or joy, but they have nothing like the words of human speech.
By the way, unlike human beings who have to learn how to talk, apes and other animals know their “language” by instinct. They will make the right kind of cries and sounds and expression even if they have never seen another animal like themselves before.
Birds, however, learn their way of singing, at least in part. That is why a sparrow brought up among canaries will try to sing like one. It has been learning the wrong “language”!
