If you want evidence of serious overfishing, look no further than Billingsgate Fish Market in London. Apparently, the price of a kilogram of cod has increased from Â£6 (C$11.87) four years ago to Â£30 (C$59.36) today. This is despite how fish is being brought in from ever-father away, concealing the degree to which local waters have been depleted.
Since 2000, cod has been considered an endangered species by the World Wide Fund for Nature. According to one of their reports, the global cod catch has fallen by 70% during the past thirty years and the fish could be commercially extinct as soon as 2020. The WWF report claims that:
[T]he world’s cod fisheries are disappearing fast, with a global catch that has declined from 3.1 million tonnes in 1970 to 950,000 tonnes in 2000. In the North American cod fishery, the catch has declined by 90 per cent since the early 1980s, while in European waters, the catch of the North Sea cod is now just 25 per cent of what it was 15 years ago.
This is consistent with the study in Science by Worm et al. that projected “the global collapse of all taxa currently fished by the midâ€“21st century.”
