THE AMERICAN SOUTHWEST
Challenges for the Future

The biggest challenge for the future of the American Southwest is water. There are other challenges such as immigration, but when you have a region of more than 50 million people that are using over 75 percent of all surface water without it being replaced, something has to give. Throw in other factors such as the expected doubling of the population in 50-100 years, or the climate change that is seeing the desert get even hotter, and you have a catastrophe brewing. And if you ever wanted to become a billionaire, solve this water problem, and it's guaranteed.
