You don't have to earn a huge amount to be in that 1%. According to this site How rich am I , if your post tax income is 70k, and only 2 in the house, you hit the 1%. Not sure if it's accurate? 1% of worlds population is about 79 million. According to the article you quoted each 'rich' person will generate 70 tonnes of CO2, so that's about 5 billion tons, the annual output of the US,. The figures just don't add up to me, but I think it highlights a problem. Not sure I agree with the scale of it.I feel sorry for the richest 1%, I'm sure they'll be doing all they can to help out.
