Several years ago, I had a visitor from San Francisco who offered to help me in the kitchen. I put her to work cutting up the veg for the salad. I knew she knew where the garbage pail was, so I was surprised when she asked me where to put the inedible bits from the veg. She was appalled that I would actually throw such things in the trash.
I guess it all makes sense now-- San Francisco is going to fine people for throwing scraps in the garbage, making composting mandatory. I've had a compost heap before, and I like it, and one day when I cook more frequently, I'll do so again. However, I wouldn't dream of living in a place which mandated me not to throw scraps in my own damned trash, a service for which I already pay.
Considering her husband spent about 3 hours a day driving to and from work, the way I see it, her carbon footprint was loads larger than mine. I'm ready to be judged.
