Thanks to tougher pollution controls, modern power plants produce only a fraction as much pollution. This is an old photo of the kind of smoke that used to come from coal-fired power plants and, apart from soot (unburned carbon particles), its pollutants include sulfur dioxide and the greenhouse gas carbon dioxide. Photo: Air pollution is obvious when it pours from a smokestack (chimney), but it's So what exactly causes this majorĮnvironmental issue and what can we do about it? Let's take a While a further 3.8 million die due to dirty indoor air.Īir pollution is a huge problem-and not just for people living in smog-choked cities: through such things as global warming and damage to the ozone layer, it has the potential to affect us all. The gases you're sucking up through your noseĬould be slowly killing you: according to theĪround 4.2 million people die prematurely from the effects of polluted, outdoor air every single year, You're a scientist with a chemistry lab at your fingertips, there's There's nothing quite like opening the door and breathing fresh, clean,Īir-but how clean is the air you're breathing right now?
