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.
