This week the multi-part RESCUE series continues with an examination of familiar products derived from the ocean that we use to support our ways of life, our well-being and our health: from vitamins and supplements to pain and cancer treatments. And we discuss the future of exploration and exploitation of resources as the bio-prospecting rush heats up. How are we regulating extraction from the ocean and seafloor? Who owns the proprietary rights to marine resources, and what criteria are applied to protect biodiversity, ocean ecosystems and future resource potential to revolutionize medicine and treat disease?
