Despite All the Beans...
...vegans are still emitting out less carbons than you meat-eaters.
An average burger man (that is, not the outsize variety) emits the equivalent of 1.5 tonnes more CO2 every year than the standard vegan.
And don't think switching to a hybrid gets you off the hook either.
By comparison, were you to trade in your conventional gas-guzzler for a state of the art Prius hybrid, your CO2 savings would amount to little more than one tonne per year.
