                                    A personal water footprint is the total amount of water a person
                                    uses. Read the questions below. Then, with your teacher’s permission,
                                    access the website. Use the tool to calculate
                   your own water footprint as you answer the questions below. The information you need
                   may display with the prompts, or in your water footprint report. While using the water
                   footprint calculator, respond to the prompts as accurately as possible.
                   1.  What is your water footprint?

                   2.  Is your water footprint greater than or less than the U.S. average?
                   3.  List at least four things that directly impact the amount of water you use every day.

                   4.  What are the two largest contributors to your water footprint?
                   5.  What is one thing you can do to reduce your water footprint?

                                            Essential Concept

                                            Water is central to sustainability.

                                            1.1   Our Relationship with Water

               WATER SUSTAINABILITY         It is impossible to separate water sustainability from a
               Equitable use and manage-    healthy natural environment, a successful economy, or human
               ment of water that does      equity and well-being. Successful water sustainability means
               not impair its availability or
               quality for present and future   that we must always consider the relationship of water to

                                            It is relatively easy to see obvious uses of water such as drink-

                                            ing, bathing, and cleaning, but there are also many ways in

               VIRTUAL WATER                is also called virtual water, is the amount of fresh water used
