In my home virtually no food, meat or fresh produce goes to waste. I do not have a car. I walk to my food coop 2-3 times a week to get produce. My town has curbside compost pickup so that I can compost what little does get discarded including meat which is allowed in the curbside compost. The assumptions people make about their own moral superiority and the moral deficiencies of others is simply part of their arrogance, their need to believe themselves to be better than others.
