Fishing for sustainability: Will your grandchildren have the option to eat seafood?
Date of this Version
Many of the world’s fisheries are threatened by over-exploitation or fish kills from run-off of industrial, agricultural and urban pollutants. The latter tends to be localised; however, over 50 years ago the explorer Thor Heyendall discovered the unexpected in the middle of the vast Pacific Ocean in his ’Kon Tild’ expedition -- large globules of congealed pollutants. While the pollution of our rivers, seas and oceans has only taken on dramatic dimensions since the rapid industrialisation and human population growth of the twentieth century, over-fishing has known no boundaries for much longer. However, only in recent times have the consequences become evident. Two prime examples are the fight over limited fish stock that led to the English-Icelandic cod wars in the 1970s, and the near destruction of the Newfoundland cod fishery in the early 1990s.
