Urbanization, demographic growth, density of pollution and the change of consummation are caused the progressive degradation of our life, and they exposed environment to the pollution risks which menace the public salubrity also the citizen health.
There are two types of pollution: the water pollution and the air pollution.
The airconstitutes one of the necessary elements for life. Air pollution is caused by the presence of the pollutants in the atmosphere. These pollutants can be natural origin or is come from the human activities (industry; transports).
The natural pollutants:
The pollutants which are bind with the natural origin are principally the Sulphur dioxyde (SO2) and the Nitrogen dioxyde (NO2), these latest come from the volcanic eruption, the forest fires, ocean and the decomposition of the organic matters ( animals and vegetables death).These natural pollutants are less dangerous because they do not stay a long time in the atmosphere.
The pollutants which are came from the human activities:
The principal pollutants that the men reject in the atmosphere are: the carbon dioxyde (CO2), the Sulphur dioxyde (SO2), the nitrogen dioxyde (NO2), ozone (O3)… They proceed from the combustion of the fossil energies (coal, petroleum and the natural gas), industries (ironworking, ****lworker, incinerators the wastes, and refineries the petroleum…) and the road transports (the fuel and the diesel oil combustion by the cars and the lorries are the responsible of the bad air quality in the big cities)
The air pollution’s consequences:
Human health:
The air pollution causes principally the eyes irritation, the vision problems, the respiratory difficulties, chronic cough and the lung cancer. The persons who are more touch by this pollution are children, old persons and the sensitive persons (smokers, asthmatics…).
Dust attacks the respiratory ways, the carbon monoxide acts on the heart and the brains, plumb and the cadmium attack the blood and the kidneys also the fuel soot and the benzene are carcinogenic.
Earth:
In the begging, the air pollution doesn’t touch only the atmosphere bass layer (the troposphere). Some pollutants are thrown in the atmosphere high layers. This action caused the global warming: the earth is getting warmer. The cause is carbon dioxide in the air. Its volume has increased a lot because of the burning of oil, coal and wood. This carbon dioxide has enveloped the earth in a sort of greenhouse which traps the heat from the sun. It does not let it go out, so the temperature will rise. In addition, if the earth gets hotter, the glaciers will melts. And if the glaciers melt, the volume of the water in the seas will increase and the level of sea water will rise. This will cause flooding. As a result, vast areas of the Indian coast, Bangladesh, Holland and even London will be under water. Moreover, the wins and rain will change. Some regions will have more storms which can destroy crops, houses and will kill a lot of people. On the contrary, vast areas of the world, the USA and Russia, North Africa will suffer from lack of rain (drought) can transform these areas into deserts. As a result, we will have less food to eat and less water to drink.
Secondly, the use of the Chlorofluorocarbures (CFC) in the aerosol bombs also the refrigerators decreased the ozone concentration in the atmosphere which caused the famous hole in the ozone layer which is discovered in 1980 above the Antarctic (above the South pole). Furthermore, loss of protection from ultra violet rays is caused by the destruction of the ozone layer causes; therefore, people will suffer from skin cancer.

Finally, some industry pollutants caused the rain acids as Sulphur dioxide and nitrogen which are combined in the air humidity for to form the acids (the Sulphuric acid and the nitric acid), after that, they are transported far to another place by wins before to be precipitate by rains. Consequently, forest, marine life, ponds and monuments are the principal victims.
Solutions:
The solutions for to reduce the air pollution are:
Firstly, Make known about the jeopardy of this pollution by advertising. Secondly, the reduction of the transports mostly the cars moving and replace them by collective transports. Thirdly, use the complexes systems which limit this pollution like the catalytic converters for cars and the atmosphere filters for the factories chimneys. Fourthly, develop the renewable energies like: solar energies, wind energies, nuclear energies. Finally, plant trees for formed forest because the trees are our lungs.

Without water, life could not exist. Because it is essential to all life as a result “Water = life” but now the water is ill this illness called “water pollution” so “water ill= life ill”. This pollution touches the water surface (oceans, rivers, lakes) and the underground water. This pollution is accorded to the human activities. There are four types pf this pollution:
The agricultural pollution with the animal dejections, the nitrate and the phosphate in the fertilizer
The industrial pollution with the chemical products which are came from factories (waste water)
The domestic pollution with the waste water of houses (toilets, wash powders, detergents, bleaches…)
The petroleum pollution is generally accidental by the shipwreck of petroleum (black tides) as Exxon Valdez (Alaska, 1989), Erika (Atlantic ocean, 1999)
Wreck of the Amoco Cadiz Black tides
The water pollution‘s consequences:
· The water pollution can have the grave effects for the human health like:
· The nitrates which exist in the drinking water can caused the fatal diseases as typhoid fever and cholera.
· The heavy ****ls (mercury and the plumb) are toxic for man
· The cadmium which is existent in the fertilizers can be stocked by plants which provoke the digestion problems (diarrhea), livers and kidneys diseases.
· This pollution can destroy the animal life (fishes) also the flora (the aquatic vegetation)
Solution
Firstly, Make known about the jeopardy of this pollution by advertising. Secondly, make laws about this pollution and forfeit for any one controvert these laws. Thirdly, it must to clean beaches and seas also wash animals which are touched by this disaster. Fourthly, waste waters should be treated before throwing them to the seas. Finally, lessons about the environment culture must be given in the school.
Cleaning beaches washing birds
Human activities are generating the solid wastes which represent the sources of pollution, for the reason that are toxic.
The pollution’s causes:
The present situation analyzes makes prove that the causes of this pollution are:
· Absence of the sorting wastes.
· Absence of the discharges
· Lack of information and user sensitilization
The pollution’s consequences:
The wastes are the origin of:
· Propagation of diseases and epidemics
· Clearing of smells and disagreeable smokes
· Water, air and ground pollution
· Proliferation of insects, rodents and wander animals
· Destruction landscapes
Solution:
For get rid of this pollution, we must:
· Develop the selective sorting wastes
· Sensitize the users for help to keep the property
· Improve the arrangement conditions and laws exploitation
· Develop the retraining activities
Papers recycle
The environment protection is today a preoccupation divided by the most of the citizens. Environment is more and more considered like a patrimony for protected, In addition, the protection of the human health comes by the protection of the environment. So is a duty which is a responsibility for everybody.
