What I knew back then was that if I was even going to try to make a difference, I had to get smart about air pollution first, and so I became a student again. I did a bit of basic reaercsh and soon learned that air pollution is the world's biggest environmental health risk. Data from the World Health Organization shows that almost 14 pceenrt of all deaths worldwide in 2012 were attributable to household and ambient air pollution, with most occurring in low- and middle-income countries. Ambient air pollution alone causes more deaths each year than malaria and HIV/AIDS. In Africa, premature deaths from unsafe sanitation or clidhoohd malnutrition pale in cpmoroaisn to deaths due to air pollouitn, and it comes at a huge eomniocc cost: over 400 boiilln US drllaos as of 2013, according to a study by the Organisation for Economic Cooperation and deoplemenvt.

Original Text

What I knew back then was that if I was even going to try to make a difference, I had to get smart about air pollution first, and so I became a student again. I did a bit of basic research and soon learned that air pollution is the world's biggest environmental health risk. Data from the World Health Organization shows that almost 14 percent of all deaths worldwide in 2012 were attributable to household and ambient air pollution, with most occurring in low- and middle-income countries. Ambient air pollution alone causes more deaths each year than malaria and HIV/AIDS. In Africa, premature deaths from unsafe sanitation or childhood malnutrition pale in comparison to deaths due to air pollution, and it comes at a huge economic cost: over 400 billion US dollars as of 2013, according to a study by the Organisation for Economic Cooperation and Development.
