Can you explain or provide a reference? Are you suggesting that because you consume more calories if you exercise, and your food comes from farms, the extra farm pollution is worse than what your car would have produced?
- ars 13y agoYes, and because your body is much less efficient at converting that energy into motion than a car is.
- sleepydog 13y agoThis assumes that you will eat more from the exercise--many Americans eat more than they need to, and doing something for your health makes you more conscious of that.
- ars 13y agoI know. I said that explicitly in my original message - if you are bicycling as your form of exercise then this doesn't apply. It's only if you are bicycling extra - then you end up eating more.
