Get ready to drink your own pee.
Oh yeah. Seriously.
"The term 'drought' has lost its meaning," Britt writes. "The truth is, we consume more water than nature provides."
I'm afraid I'm a little tired of all the Doomsday scenarios, but, for the purposes of this blog, I'll accept the argument that as humans keep proliferating and building and moving forward, there's only so much fresh water. "Desalination, a potential savior, is still too expensive to be practical on larges scales, but it holds promise for many locales," says Britt.
Hence, we'll all eventually be supplementing our water intake with our own water.
Britt points out that many communities, especially in the dry Southwest, already use recycled sewage water for municipal landscaping, with warning signs not to drink the stuff. I asked him how much it would cost to filter urine to make it potable. "It cost NASA about $250 million to develop and deploy a system to recycle urine and wastewater to the International Space Station," he says, which doesn't make it sound cheap versus desalination. However, he says that based on current city landscaping recycling, "Urban or community facilities...would cost millions of dollars."
