Pollution

One of the biggest problems that the world faces today is the problem of environmental pollution, are increasing every year and cause serious damage to the environment and can not overcome on Earth . Environmental pollution including contamination 5 basic categories as follows: air pollution, water pollution, soil pollution, noise pollution and light.



Air pollution is considered to be the form most toxic pollution to the environment. The cause of air pollution is caused by toxic gases emitted from cars, buses, trucks, trains and factories, namely sulfur dioxide by carbon monoxide and nitrogen oxides . Even the smoke from burning leaves or tobacco smoke also cause adverse impacts on the environment, causing damage to people and the atmosphere. Evidence of an increase in air pollution are shown in diseases such as lung cancer, asthma, allergies and other respiratory problems, along with the serious injury and can not be overcome for fauna animals and plants. Even the most natural phenomenon of migratory birds also hampered because of environmental pollution has prevented them come with their seasonal destination.


Chlorofluorocarbons (CFCs) released from refrigerators, air conditioners, deodorants and insecticides have caused serious damage to the environment. This gas was slowly destroying the atmosphere, causing ozone and lead to global warming.

Environmental pollution occurs when water industrial waste being discharged directly into rivers, lakes and other water environment for marine environment did not even "friendly" as before. Humans pollute water sources with the amount of waste decomposition scale, flowers, ash and other wastes in the family. In many rural areas, we still see a lot of people bathing and cooking with the water, causing the water quality becomes extremely bad. Acid rain also contributes to the pollution of water sources. Besides, thermal pollution and the depletion of dissolved oxygen makes water pollution serious inherently more hazardous than this. Water pollution can also indirectly cause soil pollution through runoff and groundwater seepage.

Noise pollution, soil pollution and light pollution are destroying the environment at an alarming rate. Noise pollution including aircraft noise, the noise of cars bus vans, sirens, loudspeakers and industrial noise as well as the effect of high-intensity sound waves very dangerous for contaminated environments, The maximum noise occurs due to one of the inventions of science, modern motor vehicles, responsible for 90% of all unwanted noise worldwide.



Soil contamination as a result of acid rain, polluted water, chemical fertilizers and so lead to crop failures. Soil contamination occurs when chemicals are discharged or leaking underground storage tanks create heavy pollutants in soil. These chemicals include hydrocarbons, heavy metals, MTBE, herbicides, pesticides and chlorinated hydrocarbons.

Light pollution include unwanted illumination, large lighting intensity and astronomy activities.


Environmental pollution can completely be prevented!
