There are a zillion ways we can reduce our carbon footprints, and there are no excuses not to do them. One thing that amazes me about many people is that they spend their money on DRIVING to gyms with hot water, air conditioning, heating, etc. etc. to do things like bending, lifiting weights, use rowing and stairclimbing machines, stationery bicycles, and treadmills. These are often the same people who use the elevator, pay a lawn guy to bend and lift weights, and who never walk or drive to a nearbyh store.
