Wow, love this thread.
I don't use paper plates or paper napkins.....unless it is the handful of napkins the waitress brought to the table and I take home because I know they will get thrown out. We buy used cars. The thermostat is at 65. I use newspapers to keep the weeds down. All vegetable trimmings and egg shells go for compost. Do all errands in 1 trip to town. Try to run dishwasher and washing machine only with full loads. I used to hang all laundry on the clothesline but now we live in the woods. Turn off lights. I'm sure there are a lot more I'm not thinking of right now.
