Obama's zeal for implementing costly measures to reduce green house gases in a economic depression (the Obama Depression) is misplaced. He should target the real source of green house gases: cows.
From the timesonline:
Livestock contribute 18 per cent of the greenhouse gases believed to cause global warming, according to the UN Food and Agriculture Organisation. The Danish Tax Commission estimates that a cow will emit four tonnes of methane a year in burps and flatulence, compared with 2.7 tonnes of carbon dioxide for an average car.
He should also consider taxing all the hot air coming from his administration.
