nature plays a central role in human life. For mankind, nature is the primary source of life and existence on earth. For a long time people looked upon "nature" as an unlimited resource for all their material goods. But later people faced big problems, because of its negative impact on the flora and fauna. And came to the conclusion that it was necessary to decide on the rational use of nature, both as a whole and its individual components. The issue of nature preservation has been gaining momentum lately, and the people of the country are not kidding about its preservation.

When talking about inexhaustible natural resources, we can also include climate resources - air and wind energy. Since the transport industry and industry are developing every minute, there is a lot of air pollution from traffic smoke, dust, exhaust fumes, and other "bad" substances. And in big cities the problem of exhaust fumes is the most common, because it has a negative impact on human health. The fight for clean air has become an important environmental issue in many parts of the country. Inexhaustible natural resources also include cosmic resources, such as sunlight and tidal energy. But again, in megalopolitan cities, solar radiation has a negative impact on human health. The only thing is that the amount of solar radiation is greatly reduced because of the smoke in the air. But do not count this as a positive quality, most likely both factors will act as negative qualities.

We all need to take care of our nature, throwing trash in special places and not scattering it in the street. Even with small actions we can reduce pollution.
