IGCSE Biology Podcast: Air pollution
Posted on March 29th, 2010 No commentsWelcome back to ClickBiologyThis podcast covers air pollution by carbon dioxide and methane (the greenhouse gases) and sulfur dioxide and nitrogen oxides, which cause global warming.
I have slightly over-edited it so a couple of words are truncated. So where it says “contributor are”, I really mean “contributers are”. Also I am saying “acidified lakes” not “lake” and “birth defects” not “bird defects” (which is what I think it sounds like). I know I should change it but honestly I already sound like three different people on it I have corrected it so often.
Anyway the information is what is important, enjoy!
