POLLUTION, CAUSES AND CONSEQUENCES

 Against pollution, causes and consequences of pollution

Pollution is the introduction of pollutants (chemicals, genetic substances or energy in the form of noise, heat, or light) in an environment to the extent that its effects become harmful to human health, to that of others living organisms, the environment or the current climate.

There is a very large number of pollution: human pollution, diffuse pollution, chronic pollution, genetic pollution, air pollution, electromagnetic pollution, radioactive pollution, thermal pollution, pollution of mass tourism, space pollution, pollution of military origin, sensitive pollution, noise pollution, light pollution, visual pollution, odor pollution.

Pollution of human origin, also called anthropogenic, has many forms: local, punctual, accidental, diffuse, chronic, genetic, voluntary, involuntary, etc.

At the legislative level, in most countries, the word pollution describes the contamination of a medium by a polluting agent beyond a norm, a threshold, a law, or a hypothesis.

It may be the presence of an element, heat or radiation in a medium or in a context where it is normally absent in its natural state.

Diffuse pollution is a pollution with multiple sources (exhaust pipes, pesticide application ..)

Chronic pollution is a pollution with repeated emissions of pollutant, or sometimes when the pollutant is very persistent.

Soil pollution can be of industrial origin, following the presence of a polluting industry not taking all the necessary precautions to avoid leaks, with the massive use of fertilizers or insecticides that infiltrate the soil. soils.

These agricultural pollutions can have several impacts on the health, by touching water tables on the one hand and by contaminating by bioaccumulation the crops growing on these grounds on the other hand.

Water pollution can have various origins among industrial farms, industry and wastewater.

The consequences of pollution on the environment:

They result in the greenhouse effect, acid rain, the modification of the ozone layer.

Pollution monitoring bodies have been set up. Thanks to the measurements made, they warn the decision makers and the industrialists.

The consequences of pollution on health:

Water pollution can have consequences for human health.

France and most developed countries have established laws and standards in this regard.

This is not the case everywhere: diseases from polluted water still kill millions of people every year in poor countries.

These are diseases caused by drinking this polluted water and diseases due to a simple contact of the skin with this water.

Air pollution or air pollution can be the cause of early death.

The chronic effects of pollution on health are two to three times higher than those estimated.

There has never been so much CO2 in the atmosphere.

Air pollution makes 1000 deaths every year in Ile de France.

Nearly 30,000 anticipated deaths are attributed to air pollution.

7 to 20% of cancers would be attributable to environmental elements including chemicals, said the Minister of Ecology and Sustainable Development, Serge Lepeltier, opening the second Health and Environment Parliamentary meetings on the impacts of chemical pollution on the environment. health.
