In this article you will find some information about pollution. Newxt days we will add some more information about pollution and we will add its link here. . .
Pollution has already become an international problem. Even countries with little industry have reason to be alarmed by the appalling situation. Industries and individuals dump waste materials into rivers, oceans, and even local water supplies.
Farmers use chemical insecticides to protect their crops, but these chemicals, which remain in the soil and water for long periods of time, also endanger many other living things. Already, many species of plant and animal life face complete destruction. Their disappearance will harm others, as the natural food supply is reduced.
This chain of events may ultimately result in a serious imbalance in nature which could endanger all living creatures, including man. Thus, all nations should make an attempt to stop pollution. At the present time, it seems more likely that man’s future will be determined by his success or failure in preserving a healthy environment than by a worldwide famine, disease or war.
Ecology means the study of the inter-relationships of plants, animals, human beings and their environments. Environment is everything that affects the quality of your life: the air you breathe, the water you drink or swim in, your flat or house, the number of people, the traffic, the noise and streets, shops, parks, countryside, seaside, factories, farming, mining.
The different kinds of pollution are all connected. What happens to the air affects the land. What happens to the land affects the water. And what happens to the water affects the air. Man has been polluting the earth for a very long time. At first, when the environment got dirty, people moved to a cleaner place, but the rise in population and the developing industry have changed that, and we can’t do it any more. There are new kinds of waste, such as plastics, and new chemicals which are very hard to destroy.
So, the earth is becoming dirtier. Every year about 150,000,000 tons of dirt, sprays and gases go into the air over the USA. Air pollution damages paint and metal, makes our clothes dirty, stops the growth of plants and can also cause many diseases and death. There are two main causes of air pollution: fumes from cars, trucks and buses, and fumes from industry.
In large cities, cars alone are responsible for about 80 per cent of the air pollution. Gasoline engines give off a gas called carbon monoxide, which has no colour or smell. This gas will make you sleepy, give you a headache and can finally kill you. Scientists say that breathing the air of New York is like smoking forty cigarettes a day.
