Air pollution


WHAT IS AIR POLLUTION

Air pollution is the introduction of chemicals, particulate matter, or biological materials that cause harm or discomfort to humans or other living organisms, or damages the natural environment, into the atmosphere
The atmosphere is a complex, dynamic natural gaseous system that is essential to support life on planet Earth. Stratospheric ozone depletion due to air pollution has long been recognized as a threat to human health as well as to the Earth's ecosystems.

  2. now only i know that even hair spray and vanish thing have the responsibility on causing air pollution!!! and even the methane gases release by animals also become one of the causing reason in this issue..
    if things are like tat, does that mean that gases produced by living organism in Earth is also one of the causing reason la?? it's fun to think about it..

  3. To answer what H3RmLtt asked...for me,i don't think that the gases produced by living organism like human being will cause air pollution...as i know,air pollution is caused by the gases like sulphur dioxide,monodioxide that contains toxic inside it...so like we - human being breathe out carbon dioxide,i don't think it will cause air pollution...moreover,if really like that,then it should be had this air pollution since very very long time ago that when our earth lived by human being,am i right?

  4. i dont think so...because the gases that came out from living organism such as carbon dioxide is been used by the plant..thats why there are no air pollution in a very long time ago, because the plant is so many...
