Environmental pollution is called to the presence in the environment of any 
agent (physical, chemical or biological) or a combination of several drugs in places, forms and concentrations as they are or may be harmful to health, safety or welfare of the population, or that may be harmful to plant or animal life or prevent the normal use of the property and places of recreation and enjoyment of them.
agent (physical, chemical or biological) or a combination of several drugs in places, forms and concentrations as they are or may be harmful to health, safety or welfare of the population, or that may be harmful to plant or animal life or prevent the normal use of the property and places of recreation and enjoyment of them. Environmental pollution is also incorporated into the receiving bodies of solid, liquid or gaseous, or mixtures thereof, provided that adversely alter the natural conditions of the same, or that may affect health, hygiene or welfare.
As you increase the power of man over nature and new needs as a result of living in society, the environment that surrounds it deteriorates more and more. The social behavior of man, which led him to communicate through language, which later formed the human culture, allowed him to differentiate themselves from other living beings. But while they adapt to the environment to survive, man adapts and modifies the same means as needed.Technological progress, on the one hand and rapid population growth, on the other, produce environmental change, in some cases to violate the biological balance of the Earth. Not that there is an absolute incompatibility between technological development, the advancement of civilization and the maintenance of ecological balance, but it is important that men know harmonization.
It is therefore necessary to protect the renewable and nonrenewable resources and to realize that environmental sanitation is essential for life on the planetPollution is one of the major environmental problems affecting our world and arises when an imbalance occurs as a result of the addition of any substance to the environment in quantities that cause adverse effects in humans, animals , plant or materials exposed to doses that exceed acceptable levels in nature.
Contamination may arise from certain forms of nature (natural sources) or because of the different production processes of man (anthropogenic sources) that make up the activities of daily living.The sources that generate more pollution of anthropogenic origin are: industrial goods (refrigerators, slaughterhouses and tanneries, mining and oil), commercial (envelopes and packages), agriculture (agricultural chemicals), household (packaging, nappies, garden waste) and sources mobile (car exhaust). Emission source means the physical or geographical origin where there is a contaminant release to the environment, whether air, water or soil. Traditionally, the environment has been divided for their study and their interpretation, these three components: air, water and soil, but this division is purely theoretical, since most of the pollutants interact with more than one elements of the environment.
