The companies running the fishing industry are bastards. The companies running the beef industry are, too. I'm not about to be smug about being vegetarian, though; I'm sure the veg food companies aren't great either. All companies have to make financial and ethical choices that would be labeled sociopathic if an individual did so, because profit to shareholders is the sole acceptable motivation for a company. This is one of the reasons why I advocate government-as-regulator; it is a way to attach profit penalties/rewards to desired behavior.
The fishing article makes the argument that the industry is a giant Ponzi scheme, which is really just stating that it's being run in an unsustainable way. So are the oil, metals, computer, and financial industries - and, therefore, the transportation and manufacturing industries that they support. Why shouldn't our food sources be managed to run out at about the same time as the wealth that lets us make use of them?
