We know that the Earth lungs are the trees, are our medicine against the contamination, since the great wooded masses you make are them of I oxygenate through the photosynthesis, that is the property that has the green plants to produce I oxygenate from the carbonic anhydride of the air, by effects of the solar light, in the presence of the chlorophyll. The airborne contamination could in fact be diminished by this contribution. We think that in the great cities, the trees, by this mechanism, also contribute to adjust the atmosphere, but is not thus, because it has been possible to verify in the regions highly industrialized that, as a result of the soot and of the smoke of tar, produced by the polluting factors do that estomas or pores of the leaves, through which the gaseous interchange becomes, esten obstructed, thus this rescuing function is not realised. This is the reason by which all the Science of the humanity this pawned on winning the battle to him to the Contamination. Credit: Drew Houston-2011. Through the WHO (World-wide Organization of the Health) they realise studies to control the polluting particle concentration in regions especially chosen. Also the symptoms and causes of the human diseases attributed study to the contamination; and because of as much death of the animal. The fight this directed to obtain methods to neutralize the industrial polluting agents suitably, to control preservative additives of foods and to obtain biodegradable insecticides, pesticides and detergents, that is to say that can Be neutralized, unfolded in nontoxic or destroyed products as a result of the bacteria of the ground or the water. Without a doubt, our civilization will take a great step if he is able to take advantage of the gifts the nature, but conserving them as they are, with all their vast wealth in alive beings of countless varieties, like insurance for the persistence of the own life of the man.
