Everyday I see buses and auto rickshaws putting out a load of smoke. I hear these private buses also use kerosene along with the regular diesel to get more power. But this causes a lot more pollution then the normal levels. The Govt doesn’t control anything about this. The officials are corrupt and they can be bought with enough bribe. So sooner or later we have to use something like inogen oxygen concentrator which is portable for to breathe – this is if there are any oxygen left over in the world.
