Day by day our changing world, the vast majority of environmental causes, many of these changes are irreversible.
But we, the generations to come in time to save our environment, recycle it, transform it and use it better, so it provides a lot of attention so that s EPAS is happening and how you can help to preserve the earth.
air pollution
Air pollution has increased markedly in recent years and is one of the most serious problems facing mankind. It is no longer a matter of a few places, the wind has been commissioned to make it a global problem. The problem of air pollution began about 200 years ago with the Revolution industrial. 
Today, the expelled smoke from cars, trucks and collective, industrial processes, heating systems and even cigarette smoke come together to pollute the air we breathe, causing a large proportion of respiratory diseases that are in large cities .
Did you know …?
One of the world’s five most polluted cities are: Beijing, Mexico City, Rio de Janeiro, Seoul and Shanghai, this does not mean that the rest of the world is free from pollution, we all 
remember cuebiertos under a single layer ozone, that it is finished because of the gases of the large factories and automobiles.
acid rain.
Acid rain is formed when moisture in the air combines with nitrogen oxides and sulfur dioxide emitted by factories, power plants and vehicles that burn coal or oil. This interaction of gases with water vapor forming sulfuric acid and nitric acid. Finally, these chemicals fall to earth as precipitation or acid rain.
Acid rain causes serious environmental effects. Acidification of the waters of lakes, rivers and seas, hinders the development of aquatic life in these waters will greatly enhance the fish kills. Also directly affects the vegetation, causing major damage in forest areas, as well as finishing with nitrogen fixing microorganisms.Acid rain can dissolve calcium carbonate, CaCO3, affecting in this way to the monuments and buildings built of marble or limestone.
we can do … Now that we know what is one of the problems which are finishing with our environment, to wildlife, flora and that we have identified the factors causing this problem we must finish the root, this is not easy should imagine it as big business and could not close the process of converting all the files in the world would be very extensive, but we do have so many difficulties through?
would stop using cars to eliminate many toxic gases, or to perform the same conversion to natural gas.
our products could be more natural if we take into account sustainable development and sustainable (if a felled tree, planted 3 more).
