I think being vegan is a noble but naïve way of living. I know a couple of vegans who are vegan to reduce the CO2 output, which is noble. The naïve part however is thinking they actually make a difference. A better solution would be to find more environmental friendly sources to generate energy. The CO2 output by animals is much lower compared to the industrial market (Machinery, oil, fossil fuel etc).
