Air pollution - a really serious problem. Air is composed of oxygen, nitrogen, water vapor, and, thanks to our civilization, of a variety of toxic particles. The more of these particles in the air is, the less room is left in the atmosphere for oxygen.
The problem of air pollution is not limited to the space outside. The air inside our homes and offices can be as dangerous to your health. The main source of pollution - cigarette smoke, but it is not the only one. Toxins are allocated even when you just cook. Every time you scratch the Teflon non-stick coating is allocated enough toxins to kill a canary.
Greenhouse effect, which we all have been associated with the phenomenon of global warming, caused by toxic gases. The main enemy of clear atmosphere - methane. It is released from the decomposition of sewage.
Greatly affects our waterways. In every neighborhood, in every city there drain sewer, storm water from the highways and municipal enterprises directly into the river. Everything goes into the water, passing minor cleaning steps.
