Catch Zero

What can be done as marine ecosystems face a deepening crisis?

Give a man a fish, goes the Chinese proverb, and you feed him for a day. Teach a man to fish, and you feed him for a lifetime. If he catches too many fish, however, he may leave few fish behind for his children’s table. It has taken less than a generation for modern industrial-scale fishing, once it’s deployed in an ocean area, to exhaust the vast majority of that area’s edible bounty.
