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 2015 theme is "Water and Sustainable Development." Water is at the center of any discussion about sustainable development. Without access to adequate and sustainable sanitation, growing conditions, energy, and infrastructure—all dependent upon water—the world's residents will suffer continued health problems, poverty, and inequality.
