  1. Gathering information to teach at a seminar for 7th, 8th, and 9th graders, I tested several water footprint calculators. Results were similar on all of them, with the highest water consumption due to consuming meat and dairy products. Even though I practice every conceivable indoor and outdoor water conservation practice known, my water footprint remains high from my love of chicken, beef, and dairy products. A similar bump occurs for the exact same reason in my carbon footprint. Oh great. More guilt.
