As bad as pollution is, could it have a use. It of course can cause increases in global temperature (but very minute) and smells really bad. However what if this pollution comes to use one day. What if this increase in temperature is preventing another ice age. Maybe some asteroid will impact earth in the future and the reason why we survive is because the polluted atmosphere broke it up.
As much as this is sounding like a bunch of crap, does pollution have an upside?
