2. The UN [Intergovernmental Panel on Climate Change] concluded that to stabilize the world climate fossil fuel use needed to be cut by 60%. Say this were done and then say that the world's population shared the remaining fossil fuel equally. Each human being would get to produce 1.69 tonnes of carbon dioxide annually -- which would allow you to drive an average American car nine miles a day. By the time the population increased to 8.5 billion, in about 2025, the limit would be down to six miles a day. Carpooling might leave about three pounds of CO2 left in your daily ration -- enough to run a highly efficient refrigerator. Forget a computer, a TV, a stereo, a stove, a dishwasher, a water heater, a microwave, a water pump, a clock. Forget light bulbs, compact fluorescent or not.
