Steven Levitt [jo, jag vet att en timmes joggning inte bränner 1000 kalorier]:
[I]f we want to blame the obese for global warming, those who engage in recreational exercise like jogging or biking for pleasure should surely be discouraged from doing so because of global warming.
Someone who jogs an hour per day burns an extra 1,000 calories daily … far more than an obese person. Such wasteful burning of calories must be discouraged if we are to save the planet.
I hereby call for the next president of the United States to pass legislation imposing a carbon tax of 10 cents per hour on all recreational burning of calories. To save the planet, we must encourage people to sit at home and burn as few calories as possible.
