This is a remarkable statement.
If everyone would just cut down on meat, even avoid it a few days of the week, it would make an enormous positive impact. Same goes for seafood.
From the perspective of someone who eats meat twice a week or so, it's absurd to hear people say they couldn't do it. Yeah, they could.
Of course, with governments subsidizing the hell out of the meat industry those $0.99 McDonalds specials will keep encouraging everyone to eat it 3x/day...
