At the HuffPo, Prof. Emanuel Pastreich pens a humorous letter to PSY:

You are in a position to show that we can be happy without consuming.

Please, Psy, please stop eating meat.

The consumption of meat is a tremendous waste of water, soil and other resources that is destroying our world. If we were to eat only vegetables and grains, there will be enough food for everyone in the world and our soil and water could be preserved. It takes 2,500 gallons of water to produce 1 pound of beef, compared to a mere 25 gallons to produce one serving of rice or grain. That difference will make or break our future.
