Dr Meriwether Wilson, Lecturer in Marine Science and Policy, delivers the seventh lecture in the 2015 Our Changing World series, entitled "Ocean Futures: Balancing Blue Growth and Conservation". This talk explores how the concepts of 'blue capital', blue growth and ecosystem services, which are typically anthropocentric, can be viewed with a broader interpretation in which the diverse marine species resident in our global oceans can be fully taken into account as well. Recorded on 10 November 2015 at the University of Edinburgh's George Square Lecture Theatre.
