Today, one out of three people donâ€™t have access to safe drinking water. And thatâ€™s the result of many things, but one of them is that 96.5% of that water is found in our oceans. Itâ€™s saturated with salt, and undrinkable. Most of the freshwater is locked away in glaciers or deep underground. Less than one percent of it is available to us. So why canâ€™t we just take all that seawater, filter out the salt, and have a nearly unlimited supply of clean, drinkable water?
