A great deal of energy is needed to run the factories of modern industrialized nations. Automobiles, trains, planes and buses need energy, too. Nearly all of this energy is maintained by burning fuels. The burning produces wastes. Some of the wastes get into the air, causing air pollution. This burning fuel gives off carbon monoxide that is harmful to our health, Carbon monoxide is a colorless, ordorless gas, and a deadly poison. When we inhale this poisonous gas, it will irritate the lungs, causing skin illness and hurts the eyes. Most electricity is generated by steam turbines. About half of the sulfur dioxide in the air comes from burning fuel to make steam. Nuclear power is thought to be a safe way of generating power. But the radioactive materials in these plants could present a danger in an accident. It is now high time we took measures. Encouragingly, people everywhere have come to know the seriousness of air pollution. A satisfactory and complete solution to this problem requires the efforts and attention of all people. Certain streets should be closed to automobiles to lower the pollution levels. The amount of carbon monoxide that an engine gives off can be reduced by special devices. Also, engineers try to design and locate new plants that will do minimum damage to the environment. |
