DONAL HICKEY: Ending the spectre of ghost nets

An estimated 640,000 tonnes of lost fishing nets kill more than 136,000 seals, sea lions, and whales every year, in addition to millions of birds, turtles and fish, in the world’s oceans, according to World Animal Protection, writes Donal Hickey.

Sometimes called “ghost nets”, they can often be found in shipwrecks and account for one-10th of all marine litter.
