Grist: Are you one of those people who suffers through 10-second showers in the name of water and energy conservation? Grist and the planet thank you for the nice gesture every drop counts. But it turns out really saving water has more to do with whats on your plate than whats coming out of your faucet. With prolonged and extreme droughts cropping up left and right, thanks to YOU KNOW WHO (pssssst anthropogenic climate change), small changes at your table can actually have major impacts on water savings...
