Our seas and oceans used to be teeming with fish and other sea creatures, but decades of destructive fishing practices and overfishing have led to stocks of fish declining and many species facing extinction. Greenpeace is campaigning for 40 percent of the world’s oceans to be designated as marine reserves, like underwater national parks. These designated areas, where no fishing is allowed, will enable oceans to recover and protect all species of sea creatures, attractive or otherwise.
