The sheer amount of food we throw away is awful. Not just consumers either. I had a client, a homeless guy, once who ate almost exclusively from the dumpsters of local supermarkets. One day he brought some of his haul to show me what he meant: day-old baked goods (I'm talking whole cakes, boxes of cookies, muffins, danish, you name it), slightly bruised fruit (I'm talking cardboard boxes filled with it) as well as whole bags of oranges and apples. He said he's seen whole cartons of eggs and loaves of bread too.
One of the grocery stores around here (Hannaford, I think) has started selling the uglier produce at a lower cost. The apple orchard I get cider and donuts from sells half bushels of "second" apples, the ones they don't put out in the regular bags of nice apples, for use in baking/sauces/whatever. I just eat them after cutting out a spot or two, usually.
