and it helps to our health.

For the developed countries this point is the mast important part of their life,an other cause of these countries have air pollution from of factories.But we

have to think about this problem and find a good solution.

the developed countries of that,e.g:Mersedes Benz have made the car with purificator,it means it can burn the fuel completely and change it to the pure (85-90%) energy without wasting and create smoke and after that this system can refresh the air of inside and outside of the car because of these thing
