Rigs to reefs
Offshore oil platforms have an immense presence, physically, financially and environmentally. Some 6,000 rigs pump petroleum and natural gas worldwide. But as they extract hydrocarbons from deep beneath the sea, these structures undergo a transformation invisible from above the waves. The ocean claims the platforms' enormous substructures and converts them into vertical reefs, home to millions of individual plants and animals. (2019-01-31)
