So many years ago, when I was working for Thermax in India, we were doing water and wastewater treatment. And I always wondered, it seems like we have plenty of water, but I really doubt it whether we have plenty of water. Maybe I'm just not counting correctly. Turns out my intuition was right. This graphic—it's a beautiful graphic that I found—actually shows how water is distributed amongst everything on earth. It is so fascinating; you could simply look at this for several minutes and things would just start making sense. The next wars are not going to be on religion but are going to be on water. It's a scarce resource,  so make your utmost effort to conserve it.
