Of all the stresses that humans have inflicted on the world’s oceans, including pollution and global warming, industrial fishing ranks high. For years, trawlers capable of scouring the ocean floor, and factory ships trailing driftnets and longlines baited with thousands of hooks, have damaged once-abundant fisheries to the point where, the United Nations says, 90 percent of them are now fully exploited or facing collapse.
The damage is not just to the fish and the ecosystem but also to people who depend on them for food and income. This is particularly true in Africa. In 2008, in two striking articles, The Times reported that mechanized fleets from the European Union, Russia and China had nearly picked clean the oceans off Senegal and other northwest African countries, ruining coastal economies.
