You rush into the elevator and push the button to get the door to close before anyone else can get in. Or is that just me? I hate being trapped in an elevator with strangers. But do I really need a big, heavy elevator to make a trip just for me? No. I don’t.

Conservation International wants us to take the stairs. It saves electricity and it’s a good way to squeeze a little extra exercise into your day.
