Even at the time that Herman Melville wrote Moby Dick whalers were alarmed at the decline in whale stocks. To-day the situation is so serious as a result of overhunting that the whaling industry, which could produce more than half a million tons of meat and edible oils a year, is destroying itself. John Gulland, of the Fisheries Research Laboratory at Lowestoft, was one of the Committee of four scientists appointed by the Whaling Commission to investigate the whale stocks. Their report last summer showed how serious the depletion had been. Nevertheless, die recommendations for cuts in the whale quotas were rejected by the four whaling countries. In this article, originally broadcast by the B.B.C., Mr Gulland suggests an ingenious solution which he regards as the only hope for saving both whales and whaling.
