Bigeye Trevally forming a "tornado" at Cabo Pulmo National Park, Mexico . A few years ago, local fisherman decided to stop fishing and bet all on ecotourism.

What used to be an almost lifeless place now has a complete life chain, even bull sharks are back and orcas come and visit often. Cabo Pulmo is a true example that by letting the ocean recover, it will do so by itself.
