Day after day, the Earth is more and more devastated, giving humanity its wealth. Every day millions of tons of oil, natural gas, coal, peat and other minerals are pumped out. A man just devours them ruthlessly, and yet they are not eternal! Every day, factories and factories are being built that poison the atmosphere, releasing millions of tons of pollutants into the air, without thinking at the same time that we are digging a hole for ourselves. Not only air gets polluted. How many rivers, lakes, reservoirs and seas became a victim of emissions of toxic waste. Take, for example, Lake Baikal. This is the most burning example of human negligence.
