The air is considered polluted when the air is harmful to the environment (animals, plants, etc.) causing other environmental problems as set out below.
The polluted air is very bad for the planet as air pollution contributes to the greenhouse effect, acid rain, ice melting, global warming, ozone hole, etc.; and also very harmful to the inhabitants of the planet because this type of pollution also causes living things die. Air is an essential element to life, without it life is impossible, which means, if the air is polluted also kills us but a little slower in humans, the most obvious problems are:


• Problems with the respiratory system



The pollution is mainly due to emission of gaseous pollutants (SO2, NO2, CO) are from stationary sources (power plants, incinerators, industrial furnaces, etc..), Mobile sources (cars, trucks, buses, planes, trains, boats, etc..) and natural sources (volcanoes, forest fires etc.)..
Our planet to achieve a temperature more or less uniform need some greenhouse gases to create the greenhouse effect, but if there is more greenhouse gases cause the planet overheat creating all the problems mentioned above.

To combat this major problem we have:
• Use the least possible fossil fuels (coal, diesel, petrol, gas, etc.).
• By recycling we are to make you spend less energy to produce new products.
• Use clean energy (wind, solar, tidal, etc.).

The human being polluted over the last few years of the rest of their lives, so something had to be made and one of them was the implementation of the Kyoto Protocol between the countries, however one of the great powers, the United States still not signed this protocol, but it is very important to be signed as America and the countries that pollute more.
