If you believe that the challenges mentioned above only happen in the 3rd world, you might want to think again.
In the United States, we have several challenges of our own.
Here are just a few of them:
The mighty Colorado River carries the lifeblood of the Southwest. It services the water needs of 40 million people living within an area the size of France. Human demand siphons off every bit of water. At its mouth, the riverbed has become nothing but dust.
The Colorado flows into Lake Mead which, in turn, feeds the Hoover Dam. The elevation of Lake Mead used to be 1,219 feet. Today is 1,086 feet and dropping by ten feet a year. At this trend, in four years it will fall below 1,050 feet and Hoover Dam’s turbines will shut down… along with the lights of the 1.7 million homes powered by these turbines, including many in California and all of Las Vegas.
Scientists predict that 80% of the forests that existed worldwide in the 1850s will have been permanently lost within the next 15 years; while one in four mammals faces extinction and 90% of the large fish are already gone.
