"Excess" seems to fit so nicely into a environmentally themed post.
"One study estimated that a single transatlantic return flight emits roughly half the CO2 emissions produced by all other sources (lighting, heating, car use, etc.) consumed by an average person yearly."
One thing that's amazed me, whilst doing a little browsing, is how many people seem to believe that Global warming is an invention of the media. Now, I'm no scientist (really? no kidding...), but I can't buy that all the fumes from our power stations/cars/aeroplanes are having no effect. Also cutting down all the trees on this planet... good plan? Hmmmm. Digging giant holes in the ground to put all our rubbish in. Not really a long term solution is it?
I hope global warming is a load of scare mongering, I really do! That means that the ice caps won't all melt and my children will definitely have a nice future on a nice planet. In the mean time, however, I'll be using public transport, recycling my waste and watching what I buy. Even without Global warming, all of the policies and practices that are being put in place because of it can't be a bad thing.
