When i go out of my house , the first thing that i see that is injuroius to health is pollution.Smoke comes out from the bus, smoke liberated from vehicles and car contain poisnous  substances. It is harful to human health. POLLUTION is the contaminated material either in solid, liquid, gaseous which is very harmful to environment. Pollution has made the environment worst. Pollution is increasing and is going at  the atmost level.

POllution can be broadly classifed as Air Pollution, Water Pollution, Noise Pollution,Thermal Pollution, Light pollution. Pollution in the cities are increasing but now it the pollution slowly and slowly  is reaching in small towns as well.

AIR POLLUTION is most created by liberation of chemical from industries,factories. The harmful gases has made the environment worst.The pollutants has creates air pollution. The Pollutant can be primary and secondary. Primary Pollutants are those pollutants which comes directly from gases . Secondary pollutant are those which mix with  primary pollutant and are liberated.The gases liberated from the industries and factories liberates harful gases like carbon monoxide and sulphur dioxide is not only harful to environment but also human beings are caught and these pollution called many diseases with them. Pollutant that causes air pollution includes dust particles,liquid droplets or gases, they can be  man-made or natural.

Sulphur  dioxide is also harful gas which causes air pollution  which is liberated from volcanoes and from variousindustries.Carbon monoxide is a colourless gas but is indeed very harful to environment . It is a poisnous gas. It comes from the product that is left after the combustion of substances like coal, Natural gas .Toxic metal like lead and copper also causes air pollution.

Dust storm that comes in the foreign and burning of the field and burning of trees , this incident happens due air pollution. Fumes ,oil paints, hair spray also causes cause air pollution.

In the recent years, the pollution level has widley increased. In countries like America, Russia, Japan , china ,india  the pollution has crossed the danger level. Many plants are decayed and and if you bring one plant from on country to another then it will decay just because of polution.

Air pollution causes many hazardeous diseases like Asthma, fever, even it has cause several heart attacks.As we have heard the Bhopal Case, that because of leakage of gases  around 1500 people were killed. Smog is also the main problem for causing pollution. Due to air pollution Ozone layer depletion is causes. Ozone layer is decreasing and it has decreased that only few mm of ozone layer is left.Ozone layer is the layer which protects us from the Uv(Ultra violet ) rays to enter the atmosphere.

To stop Air pollution more trees must be planted and deforestaion should be banned. Some steps should be taken to control air pollution.

WATER POLLUTION is cause by the dirty water in river, lakes, ocean and groundwater. Water Pollution  mainly harm the plants and living organisms . Raw, sewage water causes pollution. But another cause of water polluton is liberation of dirtyand poisnous water from industries and factories.  It causes effects not only to human beings but also aquatic animals. Mainly water pollution is caused due to the liberation of dirty water in a clean water. This make the water polluted Eutrophication is the another cause of water pollution.

Water Pollution has also created many problem to human health and has called many diseases. Leakage also cause some problem because dirty water enter into the drinking water and causes many harmful diseases Drinking water should contain some quality and if the disastrous incidents like volcanoes, storm and earthquakes occur then the quality standards of water changes.

Causes of water polution are several. Oil leakage in the oceans cause  a huge effects to aquatic life and the whole ecosystem is distrubed .Chemical liberated from industries in water.Muddy water pollurtes the water .detergents, Pathogen pollutes water and causes severe diseases.Petroleum products should be kept away from water bodies so that polution  is not created in water.

Measures should be takento control water pollution. Before liberation of industrial waste , its should treated and ten should be left in the river. Chemical test should be done to check the level of water pollution. Agricultural waste should be treated pior releasing in th big river.

THERMAL POLLUTION has risen due to rise in temperature.The main cause of thermal pollution is the use of water as the coloent in power plants. Due to release of cold water from resevoirs thermal pollution is possible.

NOISE POLLUTION is also another a kind of pollution. Although it does not seem a problem but it is too a hazardeous pollution. It can make person deaf. Many people have been caught by the noise pollution and cause very badly effect on them.

Loud speaker should be put at a audible range.

GLOBAL WARMING is the reason of the pollution. Ice is melting in the antartic . Atmosphere change is due to the pollution.Animals are dieing  . Aquatic creatures are badly affected by  polllution.

Measures should be taken. Some strict rules have to made to control pollution , otherwise our earth would come in great danger .
