many reasons, most of the above.
I dreamed i was being shot at and i was outraged , then i noticed i was a RABBIT.
I stayed 2 weeks with some vege. friends and found their diet perfectly fine....some of their dishes were of the vege. Indian variety.
I never liked 'meat' anyway....yuk.
I noticed how beautiful Mallards are, and swore off 'duck pate'.
I noticed that in aquariums fish have pretty little faces and I gave up fish.
THEN I read that a person eats about 200 pounds(?) of 'meat' a year AND I realized that I personally could make the choice to stop supporting the meat industry to the tune of that amount.
