Hey, baby fish...I'll show you my water footprint if you show me your hot stain. What's a water footprint? Well, it's the total amount of water you or I use directly (drinking, washing, gardening) and indirectly (food and other purchases). What's a hot stain?
A hot stain is a region of the world which is beginning to run out of safe water to drink.
That's just in deserts, right? Nope. Hot stains are in every continent (save for Antarctica). Here in the US, every major metropolitan area in the Southwest is a hot stain. LA, San Diego, Phoenix, Las Vegas, San Antonio...and all the other cities that depend on water sucked from the Sierra Nevada and/or the Colorado River. So...in the US "hot stains" are just a Southwest thing? Nope. Atlanta - along with much of Georgia and Alabama and many cities in Florida - is part of Hot Stain Nation.
