Our planet Earth Is only a tiny part of the universe, but nowadays it's the only place where we can live. People have lived on our planet for many years. They lived and live on different continents, in different countries. People depend on their planet, the sun, animals and plants around them. Environment is everything in the world around us that surrounds and affects all life on earth, including the air, food, water, plants, animals and other. Since ancient time nature has served man, being the source of his life. For thousands of years people lived In harmony with environment and it seemed to them that natural resources were unlimited. But man's interference in nature began to increase with the development of civilization. Our ecology becomes worse and worse with every new day.
