Of all the water on our planet, only 1 percent can be consumed by humans. With rising demands on our water supplies, we're on the fast track to run out - half of the global population will be living in areas of "acute water shortage" by 2030. 2009 brought us both scary news like this, as well as a lot of interesting technology and thinking that will help us as water becomes a looming topic of conversation and activism. In this recap of 2009 in water, you'll find stunningly beautiful images, hair-raising new studies, and technologies that will conserve water and make it more fresh water as our supplies run low.
