Speaking of economic effects, a friend of mine has said that's the main reason most of the world will be vegetarian within the next 100 years-- not because of animal rights, not because of health effects, but rather economic reasons.? We won't be able to afford to waste as much land on large farms.? Shame, because I'll miss my meat-lover's pizza from Pizza Hut.
Well.........good chance you won't be alive 100 yrs from now. Especially if you are chowing on those meat lover pizzas.....
