Smarter people have made the comparison, but it's a stark one, and worth repeating: the world's oceans are remarkably similar to public bathrooms. No one owns them, and the people who use them have no incentive to keep them clean.
So it is with fishing policies throughout much of the world. While government regulations have shortened fishing seasons and brought lawsuits on some unruly actors, commercial fishing largely remains a "take all you can get any way you can get it" business. As a result, as much as one third of the world's fisheries have collapsed, and many others teeter on the brink.
How can we reverse the sorry state of the seas? How about selling them off? At first glance, it might look like handing a chunk of ocean to a fisherman or an entire fishing company is ludicrous; they'd just hoover up all the fish in the area and move on. But according to a new study, the government of Chile has met with great success in turning over its maritime resources to private industries.
The public bathroom analogy is an idea more often referred to as "the tragedy of the commons." Since the 1960s scientists have understood that any unowned natural resource is likely to be ravaged by people seeking to use those resources, either out of greed or a simple need to survive. It's a clear pattern in humanity's use of almost everything the world has to offer - water, forests, wildlife populations, even air. Nobody owns them, so everybody exploits them.
