Prepare to make a case both in support and against the following statement:
More of the world should rely on virtual water trade

Calculate your Water Footprint in three ways, taking note of the information the calculators are using to make their estimates, along with your results. First, use the quick calculator (first citation below), then work through the extended calculator (second citation below) and see how your footprints compare. Third, work through either calculator, but change your country or some other input. Bring your results to class on Monday.
