    smoke from anything is always caused by humans exept for natural bush fires and all of it polutes

    and there are all kinds of smoke
    industrual chimneys are very bad so are chimneys from power plants and burning rubish

    then there is exaust fumes from the internal combustion engines in all its forms.
    and gasses produced by decomposition of rubish made by humans
    the gasses from billions of spray cans

    air polution has been found in the north pole and antarctica
    we live in a closed Environment
    if we contaminater in one place it does not leave the system but just goes somewhere else ,taken by winds and aircurrants

    these contaminants destroy the ozone layer ,which `rotects us from the harmfull rays of the sun and can cause acid rain which destroys where ever it falls or we breath poluted air and become sick
    After 3 weeks in Mexico city i was coughing blood because of the poluted air
    most polution comes from the cities and industry

    Normally humans choose activities from other than the location they are at, so they get into their car and that’s the problem, the car, when they drive that polutes the air that we breathe, so human activities polute the world by the auto’s used to get there.
