Hm. Not convinced price or even ethics (sadly) is much of an incentive for radical change. The high price of meat might make us eat less of it, or eat it less often, or choose cheaper cuts (chicken livers, come on back!), but give it up totally and become vegetarian? Not likely. Has the price of cars or gas -- or the ethics or costs of pollution, tar sands, congestion and general inactivity -- made us all become cyclists? Has the price of houses turned us off of owning? Didn't think so.
