And Mr. Fu does not mean the sentient beings from the Vega system. Looks like all the vegan and organic food craze would be warming up the planet faster if it were possible for us to do so (run the numbers on gaseous dihydrogen monoxide versus carbon dioxide people). Seems that organic farming techniques produce more carbon dioxide than conventional techniques. But they have the added benefit of costing more. Which reduces the total purchasing power of some commies.
Eat that Vegans!
