World Water Day
Did you know that it takes 2,000-5,000 liters of water to produce one person's daily food? Or that 70% of the world's water use goes toward agriculture? Water is a renewable, but finite resource.
World Water Day is celebrated every year at the behest of the United Nations as a means of focusing international attention on the importance of freshwater and advocating for the sustainable management of freshwater resources.
The 2014 theme is "Water and Energy." Water and energy are tied together intimately. Because supplies of both are limited and because both are so important to communities worldwide, it is necessary to think of the two together when developing conservation and usage policies that affect either.
