Ever been faced with a decision about whether or not to go to the store? Or drive instead of walk to do that errand? It seems simple, but merely being conscious of our small choices can really make a difference. One little trip to the store is only a couple miles at most. But one extra trip to the store each week adds 377 lbs. of carbon dioxide each year. (Calculated assuming a 4 mile round trip weekly at http://www.americanforests.org/campaigns/shaklee/)

Given those annoying targets from the government about exercise, a few miles walking a day will basically give you a large chunk of that exercise whilst saving your fuel costs!
