How to save the oceans............................

My favorite optimist suggests we get serious about not over-fishing.  Two excerpts:

 "On land we wiped out the mammoths and sabre-tooths first, then bison, gazelles and rabbits and by the end were left eating grass seeds. In the sea, it was the same and in many areas we are now down to the prawns and shellfish. No other predator has the flexibility to do this “fishing down the food chain”, which is what makes our species so lethal."

"We tolerate the utter devastation of the seabed by nets and dredges, increasingly assisted by powerful engines, synthetic materials, sonar and electronics. Seabeds could be a veritable aquarium of reefs of water-cleansing shellfish and corals, even in the North Sea, instead of a waste of silt and rubble. We would not drag nets through forests."
