Invisible Dust

London | Thursday 21 September
Pollution level: Moderate

Blue Skies


20/04/2010

Like Beijing during the Olympics 2008 where air pollution measures (restrictions on car use and industry) enabled blue skies over the city, the ban on air flights has reduced the carbon dioxide emissions by 2.8 million tonnes (Environmental Transport Association) and we are yet to get statistics on the health benefits. The volcano eruption has produced carbon dioxide itself but in small amounts compared to the savings. Maybe the greatest benefit is the challenge to our ‘flight happy’ lifestyles by something that is so deep within our planet and those living under flight paths are enjoying the peace and  fresh air. For more information read the Guardian report 20th April 2010

Throughout time we may have reviewed volcanoes as disastrous.’But they are also givers of life. Much of the air we breathe and the ground we walk on can be traced back to ancient volcanic eruptions. And the extinction of the dinosaurs 65 million years ago (which paved the way for the coming of humans) might be traced back to a one-two punch caused by an asteroid collision and simultaneous volcanic eruptions’. Mr. Kaku, Professor of Theoretical Physics at City College of New York, for Wall Street Journal.
