(NaturalNews) The city of Sao Paulo is home to 20 million Brazilians, making it the 12th largest mega-city on a planet dominated by shortsighted humans. Shockingly, it has only 60 days of water supply remaining. The city "has about two months of guaranteed water supply remaining as it taps into the second of three emergency reserves," reports Reuters. 
Technical reserves have already been released, and as the city enters the heavy water use holiday season, its 20 million residents are riding on a fast-track collision course with severe water rationing and devastating disruptions.
But this isn't a story about Sao Paulo; it's a report that dares to point out that human societies are incredibly shortsighted and nearly incapable of sustainably populating planet Earth. In numerous regions around the world -- including California, India, Oklahoma, Brazil, China and many more -- human populations are rapidly out-growing the capacity of their local water systems. Even though keeping populations alive requires food... and growing food requires water... almost no nation or government in the world seems to be able to limit water consumption of local populations to levels which are sustainable in the long term.
Instead, the endless greed of the "grow-consume-profit" business model that dominates the global economy leaves no room for any hint of balance with nature. The overriding philosophy of modern business is to dominate nature with chemicals, mining and monoculture to maximize profit while kicking any really large problems down the road for the next generation to deal with.
The result is a world where nobody thinks about the long-term implications of today's trends because everybody's too busy trying to extract a buck or two out of the very system that will destroy their future.
Vegas, Phoenix and Tucson will also run dry
Consider Las Vegas while you ponder all this: Here's a city with no water future whatsoever, continuing to build new casinos and grow its population even as the water level of Lake Mead has already dropped to emergency levels (and continues to plummet). What do the people of Las Vegas imagine they will drink when all the cheap, easy water is gone? Will they swallow dust and pretend it's water?
The sobering truth is that nearly everyone who lives in Las Vegas doesn't think about this. By definition, anyone who realized the truth about the disappearing water throughout Nevada, Arizona and California would have already sold their property and moved away. Those who still inhabit regions with unsustainable water supplies -- such as Sao Paulo -- are choosing to make believe the problem doesn't exist.
This delusional psychology is, of course, reflected across modern human civilization and its governments, where delusional rhetoric and make believe fantasies about "endless economic growth" keep the obedient masses toiling away day after day, hoping they are securing a future which has already been mortgaged away.
Dwindling water supplies are like government debt spending
We're often tricked into believing the government will solve all these problems for us. Yep, some Americans foolishly believe the same government which just issued $1 trillion in new debt to pay the interest on its existing debt is somehow really, really good at planning for the future instead of mortgaging it away. 
If fresh water were a bank account, the world's spending deficit against that account would be deeply in the red and approaching a tipping point of default. And in precisely the same way the U.S. government borrows money to cover today's expenses with no intention of ever paying it back, human society is also borrowing water to cover today's water demands with no intention or capability of ever paying it back.
Right now in California and around the world, farmers are pumping water out of the ground that should have remained there until the year 2030. As they keep pumping the aquifers dry, they'll be reaching ever more precariously forward into the future, using up water in 2015 that should have lasted until 2050 (or beyond).
In this same way, aquifers that should have lasted 100 - 200 years will be bone dry in the not-too-distant future. Farms that once produced food will instead produce a new Dust Bowl. Populations that depended on cheap food to afford basic living expenses will find themselves starving and bankrupt (and living on government food stamps, with the accompanying loss of freedom that always follows government handouts). The world's governments -- all of which rely on food affordability to keep populations relatively docile -- will find themselves facing mass revolts and social chaos.
