Scientists have warned that the Great Barrier Reef, meant to be one of the most strictly protected natural wonders of the world, is dying, and this is because of the western appetite for prawn cocktails, and a combination of other human activities, including tourism and oil mining. The Australian Conservation Foundation has said that the reef could soon be listed as "endangered". It is one of the world’s richest natural sites, with more than 400 species of coral and 1,500 fish species. Every living thing in the 140,000-square-mile park is extremely sensitive to disturbance. The scientists’ report reveals that large-scale prawn fishing - both illegal and licensed - has in a few years reduced seabed animals by more than half. For every tonne of prawns caught up to 10 tonnes of marine life is being sacrificed.
