Ride a bike, walk, take the bus or the train. Use bike-carts for hauling. Each gallon of gasoline burned means five pounds of carbon into the atmosphere. The U.S. burns over 115 billion gallons a year. Cut down on working just for cash.
Personal arrangements reduce commuting and boost community.
Garden or farm locally so you can share in the food. Establish local currency. Depave your driveway or someone else's. Tear up a parking lot. Good soil for growing food is often under asphalt and concrete, except when a bed of rocks was put in and soil scraped away.
