All about the air we breathe. Breslav I.S., Bryantseva L.A.

The progress of civilization presents to humanity all new challenges. One of these challenges is the damage that causes rapid development of industry and transport to the air that we breathe. Every year, due to air pollution, seven million people die! The main source of harmful impurities is hydrocarbon burning products. The rejection of the "oil" needle is the main condition for cleaning the air that we breathe - in the interests of human health. Alternative energy sources are already being conducted. A car has already been created that does not work on gasoline, but on the water, the only departure of which is. The same water! But what do brave researchers breathe to where there are no air, from deep -sea dives to space flights, breathe? And how will the astronauts breathe on Mars, where the air is unsuitable for human breathing? The book that you hold in your hands tells about all this and much more. In its final part, the authors will try to reassure readers: the threat of a close catastrophe similar to global warming has not yet been proven. And for complete optimism: the supply of oxygen in the atmosphere of the Earth is enough for humanity for billions of years. If aliens get to us, death awaits them. From the air we breathe!
