water pollution

Air pollution is very important because man pollutes with cars but also with cigarettes....

I think that to stop this problem it will be necessary to build electric cars and impose them but this pollution problem creates problems in humans like the same, but also cancers (lung, kidney, ...) but we can also have indigestion because the more the planet is polluted, the more the vegetables and fruits are polluted.
But also to stop smoking (if you can't do it on your own you can call specialists or go to a detox center or smoke electronic cigarettes like that you can regulate the nicotine because cigarettes damage the lungs but also the air because the others breathe cigarette smoke.

Yes, air pollution is quite the problem, on that we can agree but I do not think electric cars could be the solution to that. The electric batteries still are a problem, for exemple once a battery is dead, it cannot be recycled or the producing of those create greenhouse gas which is the origin of the global warming on Earth.

So, electrics cars is not the greatest idea in my opinion, we'll need to find another solution.
