The ocean is our last frontier still largely unmapped and unclaimed, but that's rapidly changing. Russia, China, the US and other nations are vying for seabed and exploratory rights to resources like oil, minerals, potential lifesaving medicines, alternative energy made from algae, food derived by seaweed and many more riches. Entrepreneurs are investing in new ocean-based technologies like aquaculture, seabed mining and bio-fuels. This "Blue Economy" could generate jobs. But will the ocean be able to withstand the onslaught of its new industrial age?
