摘要

For some years we human beings have recognized that our own development, especially in the industrial nations and their population centers leads to a variety of problems, which we call, in simplified terms, environmental problemsIt is a part of human existence that they necessarily produce waste materials and that refuse arises as a result of their activities.In the so-called civilized industrial nations, however, refuse is produced by humans on a more or less unconscious basis as a commodity in the process of striving for economic growth, and with a certain amount of sarcasm one can determine that this haseven become an important economic factor.Large quantities of refuse produced directly, diverse types of emission and contamination as well as a variety of energy conversion processes lead to negative effects on our environment and quite directly on our health.
