In Britain, natural gas is the most popular fuel for heating homes, and for cooking. It is piped all over the country from the gas fields below the North sea. Natural gas is used chiefly as a direct source of energy, although it is also used in the chemical industry. At the moment, the supply is plentiful, but it will be running short by the end of the century, and it will run out during the 21stcentury unless new supplies are found. We could do without natural gas, as coal gas can be used as a substitute, and there should be enough coal to last for several centuries. However, it is a form of energy which is not only cheap, but also highly efficient.

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.
