What is air for a person? This, in my opinion, is all. After all, a person can live at least 7 minutes without air! Air fills every organism with life and not only human. Animals and plants also need air and development, and reproduction and distribution on our planet. And it is an incredible miracle that only one planet has this miracle of air – on the planet Earth! It is the air that makes this planet unique, suitable for life, and it is thanks to it that life has developed on this planet.But, unfortunately, sometimes you breathe in the air – and you don't feel the energy. Because the air is dirty. Through their activities, people pollute the earth's atmosphere and make the air harmful. Various large enterprises emit a huge amount of harmful substances directly into the air, which make the air uninhabitable. Every day, millions of cars emit tons of harmful metals into the air.Therefore our task is to preserve nature so that the air is clean
