My understanding Zouse, is that less acreage of land is needed to feed vegans. Meaning that we do not need a cull or necessarily limit population just need the population to eat in a more vegan like way?
This is what has converted me from thinking that a meal is not complete without meat to eating in a more vegan like way. This makes me feel better about the way I eat.
Amusingly at work I cooked a vegan curry today with chick-peas and someone said, "You're not a bloody vegetarian are you?". I just replied, "I didn't realise that chick peas didn't have chicken in them!".
So it is; but there is still stigma attached to peoples eating habits and I don't get the lack of ambivalence towards them.
I was berated by my normally chilled mother in law for becoming vegan after running the V3K this year. I had to explain that I was vegan (plus possibly non-vegan beer) for most of the weekend and now had a new understanding and respect for vegans!
Her argument was that vegans were being cruel to animals because if we humans did not eat them (animals not vegans!) they would not be born in the first place?
