I was wrong about veganism. Let them eat meat – but farm it properly

Also, many of the stats cited by eco-vegans turn out not to be valid. Water requirements for livestock are based off worst-case scenarios (California cows fed from irrigated crops) and are off by 3 orders of magnitude in the common case; greenhouse gas estimates for livestock conflate logging and land speculation with faring.
That said, the line "we could eat meat ... (albeit much less) with a clean conscience" is a little glib, surely most people know that the ethics of killing things just to eat them is at least an open question for reasons beyond environmentalism?
