All around the world, the oceans are in crisis. Fisheries are collapsing, as long-liners and factory trawlers vacuum the oceans clean, devastating entire species and ecosystems. Our appetite for fish and seafood is leading to what many scientists think is a global fisheries disaster. According to Dr. Callum Roberts, however, there's nothing new about this. As soon as humans first took to the oceans, we started over-exploiting them. But in his new book, The Unnatural History of the Sea (Island Press Books), Dr. Roberts tells us that history can teach us how to save the seas today.
The Unnatural History of the Sea by Dr. Callum Roberts (audio) First aired on Quirks and Quarks, October 20, 2007
