Summary in English
Our atmosphere has many essential functions. It is a reservoir of gases upon which life depends: carbon dioxide and nitrogen for plant growth, oxygen for us to breathe, water vapor for rain that refreshes the land. It insulates the planet against temperature extremes and filters out harmful radiation from the sun. It even helps detoxify harmful substances released into it, either hastening their breakdown or diluting and dispersing them. Because living things depend so completely and in so many ways on the atmosphere, any change in its makeup should concern us.
