Air Pollution

Air Pollution
Air pollution happens because of the additional chemical which endanger humans of living organism around.
  The burning of oil fuel, the burning of wood produce carbon dioxide (CO2) in the atmosphere. The CO2 gas in the atmosphere can block heat reflection from Earth surface, so the heat on Earth surface increase resulting in the an effect celled greenhouse effect. Besides the increase of CO2 level in the atmosphere. Green house effect can increase Earth temperature, the change of global climate which is feared to able  to melt the ice in the poles. If polar ice melt, then the surface of sea water increase so several cities and beaches will  be drowned
  Sulphur oxides gas (SO,SO2) which increases in amount will react with rain water to produce sulphuric acid, causing acid rain. Acid rain causes plant and leak be broken.
   CFC enters the stratosphere and destroys the ozone layer. The ozone layer has a function as a filter ultraviolet radiation from sunlight. If the ozone layer becomes thinner, it will increase the intensity of ultraviolet radiation and cause skin cancer.
  
That causes by : 
1. The burning of oil fuel, and Charcoal,
2. Forest fire,
3. The smoke excreted by factories, engines,
 motorcycle, cars, kerosene stoves, airplane, and
4. The burning of wood
5.
Sulphur oxide gas (SO, SO2)
6. The use of CFC (
Chloro Flouro Carbon) 


The effect : 
1. Greenhouse effect, because increase carbon dioxide (CO2) in the atmosphere 
2. Acid rain, because
Sulphur oxide gas react which rain water to produce sulphuric acid, causing acid rain
3. Destroy the ozone layer, because the use of CFC
(Chloro Flouro Carbon)
4. Can cause  Respiration diseases



Method to overcome air pollution :  

1. Not to burn rubbish in the yard
2. Immediately put out the stove/wood fire if cooking is finished
3. Not to smoke in the room, mainly in air-conditioned rooms
4. Not to use a refrigerator or AC which uses CFC
5. To grow decorative plants in the yard or flower vases

6. To participate in reforestation, keep (not disturb) city parks and protecting trees, also not to cut forests, trees, and wild plants arbitralrly
7. Government forbids the circulation of dangerous insecticides such as DDT and the use of CFC gas 
8.
Indrustries/factories must make chimneys
9. To decrease the use of fossil fuel by limiting the operation of old cars fuel engines
