Walking as climate help

What if we walked for all of the trips we make that are 2 miles or less? What if we replaced some of the miles we drive with the daily recommended amounts of physical exercise? Could we solve some of our energy problems? I know one thing we would do: we would have to take a LOT more time to get things done, and that might not be a bad impact. Slowing down and taking more time can actually ease stress, and getting more exercise can ease depression.

I've been wondering lately what it would mean if everyone at Luther Seminary pledged to spend one week without using their car. What would that look like? Would we learn how to use the bus system? Would some of us have to work from home, because there's no other way to get into town? What would be the impact?
