Really! Did you know that certain types of sandwiches cause global warming? After all, the scientists can't be wrong and some doing research at the University of Manchester say so. Well, no doubt every liberal in Congress will immediately dump the sandwiches and start eating sprouts wrapped in arugula (brought from home and carried in a reusable pouch). Oh, and by the way, what about the environmental impact of processing hops and corn to make alcohol? Really! When are they going to ban alcohol because of its global impact?
