My footprint size was a 5.6!
I think to reduce the size of my footprint I could:
Walk to and from school when it s warm enough. Then that would help with not so much gas going into the air.
I could turn off the water instead of letting it run. That would help to save water and water energy.
Turn off the lights when you don't need them on. That saves energy and a ton of power.
Walk and roller blade to the store in the summer time. Again that would help with gases.
Buy more freshly cut meat instead of the meat that uses all the preservatives.
