The harvest of wild terrestrial and aquatic animals each year injects more than $400 billion dollars into the world economy—but also breeds piracy, slavery, and terrorism. The over-harvest of wild animals, both from land and sea, has created a market defined by low supply and high demand. This has led to the proliferation of organized crime in some of the poorest parts of the world. Over-hunting and over-fishing have, at least in part, created conditions where human trafficking and terrorism can thrive.
