'Oceana': Amazing Images Of Our Endangered Seas (PHOTOS)

I've been involved in ocean conservation for decades, and in that time, a lot has changed, but a lot has stayed the same. Last year I decided it was time to write it all down before I get too old to tell the difference. With help from some of the world's most respected authorities in the fields of marine science and commercial fishing, as well as other influential activists, and a very talented co-author, Mike D'Orso, I wrote "Oceana: Our Endangered Oceans and What We Can Do to Save Them "-- a book that describes the most critical threats to the oceans and how we can turn them around. What follows is an eye-opening look at some of the biggest issues we face -- images that I hope will inspire you to take action and help us turn back the clock on this looming crisis.
