“I read once that pound for pound, lettuce is four times more polluting and carbon intensive than a pound of beef.”
That’s new to me but I don’t doubt it. All this carbon foorprint business is insanity, first they tell you that co2 is a “pollutant” albeit a pollutant without which there would be no life, then they tell you that this fake pollutant is more of a threat to life than people who shoot innocents until they run out of rounds and then reload. On top of that you find that most of what they want to do to reduce co2 “pollution” is counterproductive by their own standards. Ethanol added to gasoline is totally counterproductive by their own measure, it takes huge amounts of water, not to mention land, fuel, herbicide, pesticide and fertilizer to produce corn and convert it to ethanol and then ten percent ethanol gives eight percent lower mpg than straight gasoline so it is a waste to even use it if it rained from the skies free. I doubt that I have the ability to invent something as crazy as putting ethanol into gasoline and I have come up with some crazy ideas without even trying.
As for burning your food and growing high fertilizer, irrigation, cross continent transported, momentary shelf life, refrigeration needed crops in order to feel eco-smart is even dumber than adding solvents to engine fuels.
Eat local, in season, return to home canning, raise your own chickens for eggs (which eat your garbage), raise a steer and a hog to be butchered every November.
