Раньше для изготовления ножниц использовали только железо, а сейчас сами ножницы железные, а куда пальцы вставлять пласмасовые.

Economists have long thought of the environment as an unlimited source of resources. For thousands of years people lived in harmony with the environment but with the industrial revolution our negative influence on Nature began to increase. Large cities with thousands of steaming, polluting plants and factories can be found nowadays all over the world. The by-products of their activity pollute the air we breathe, the water we drink, the fields where our crops are grown.
There are many consequences of damaging the environment. One of them is "acid rain". Cars with their engines and factories have become the main source of air pollution in industrial areas. When factories send gases and chemicals into the air, they mix and the mixture is carried for hundreds of miles by the wind and finally, it falls back to earth. This "acid rain" kills fish and trees and slowly it kills everything.
Another consequence is destroying the ozone layer of the Earth. The third problem is damage to wildlife. Vast forests are cut down in Africa, South America and Asia for the needs of industries in Europe and in the USA. As a result, some species of animals, birds, fish and plants have disappeared and keep disappearing.
Another problem is damage to water and soils. Dumping wastes into lakes, rivers, seas and oceans causes water pollution. Harmful wastes may also get into the soil or drain off fields that have been sprayed with pesticides.
There is another aspect of the environmental problem, the importance and urgency of which steadily grow. How country disposes of its waste may have a major effect on its future and the future of the world, too. Recycling waste and rubbish receives ever-greater care in Europe. Cans, paper and empty bottles and other things we call rubbish are accumulated in every home. Recycling process has double effect, the other part of it being - saving energy, which would have been necessary for producing new things.
Today, many scientists and ordinary people realize that the Earth is in danger. Either we stop killing the Earth or we kill ourselves. The protection of the environment is a universal concern. Active measures should be taken to create an international system of ecological security. Some progress has been made in this direction. Many people belong to Green organizations in countries all over the world. Groups like "Green Peace" have already helped to stop some animals hunting but there are so many things to be done on our planet and our life on the Earth depends only on ourselves.
