Have you ever been thirsty? I mean really thirsty. Parched. Cotton mouth. Where it’s painful to even swallow. How about in a situation where you had no water and didn’t know where to get some? Perhaps on a hike or other adventure that was longer or hotter than expected. Think about that moment of thirst. Then think about the moment when you finally got a sip--or even a whole glass--of water. How refreshing was that water? How wonderful did it feel? To a parched mouth, water is immensely satisfying. Indeed, there is nothing quite like water to quench a thirst. This past summer, Tom and I had the opportunity to visit Iceland and drink some of the purest water on earth -- fresh glacial melt. This is water that had been frozen as ice for about 900 years -- long before the earth was so polluted by mankind. As it melts, it runs in streams through the glacier, pure, fresh, cold, and refreshing to the core.

Tomorrow is Thanksgiving. As we sit around the table with our turkey and stuffing and mashed potatoes, many of us can think of a thousand things to be thankful for -- but that clear liquid in your glass is one great gift that is often overlooked.

Water. Clean water.

Did you know that one in 10 people lack access to clean and safe water? Imagine serving Thanksgiving dinner with water that looked like the glass on the left instead of the glass on the right.
