At the start of the new movie Interstellar, the Earth has become one big dust bowl, plagued by failing crops and lung-clogging air. The only hope for the human race is to find a new planetary home in some distant star system.
It's science fiction with an uncomfortable ring of truth, emphasized by bits of historical footage from Ken Burns' documentary about the very real American dust bowl of the 1930s. That dust bowl was largely a manmade ecological disaster, brought on by plowing too much of the prairies. And it could happen again. In fact, in some parts of the world,
it already has.
