Artificial Reef Systems

Guest: Alex Goad, Reef Design Lab in Australia  Coral reefs are the “rainforests of the sea,” according to the Earth Institute at Columbia University, because they’re home to a quarter of all marine species. But the World Resources Institute says 75% of the world’s coral reefs are at risk for damage and destruction. Young Australian sculptor, industrial designer and scuba diver Alex Goad has a new project called the Modular Artificial Reef System, or MARS, and it just won him a Popular Science 2015 Invention Award.
