What if we could save the fishing industry and protect the ocean at the same time? Marine ecologist Enric Sala shares his bold plan to protect the high seas -- some of the last wild places on earth, which fall outside of any single country's jurisdiction -- by creating a giant marine reserve that protects two-thirds of the ocean. By safeguarding the high seas, Sala believes we will restore the ecological, economic and social benefits of the ocean. "When we can align economic needs with conservation, miracles can happen," Sala says.
