Whether we realize it or not, each of us affects the natural resources around us. Use a search engine of your choice to find a global or ecological footprint calculator. Input your personal information into the calculator. Report your results to this discussion.

Then discuss which activities you are engaged in that contribute most to your footprint. Give examples of what you personally can do to decrease your footprint.
