Use old oil rigs as fish nurseries, scientists say
Australian marine scientists are proposing leaving thousands of decommissioned oil rigs in their deep-sea spots indefinitely to become long-term fish nurseries. The huge chunks are of steel are meant to be removed when they reach the end of their productive life, but the scientists say their approach could save the oil industry millions of dollars and protect vulnerable fish nurseries. The Deepwater Horizon disaster a year ago showed deep sea oil exploration at its most destructive. Eleven workers were killed and almost 5 million barrels of oil leaked into the Gulf of Mexico.
