In this episode, Anders Halverson talks to Daniele Bianchi about the impacts that marine fish have on the global carbon cycle. In short, the ocean is a very important sink for carbon dioxide. Marine fish are important drivers of a biological pump that can sequester that carbon for long periods of time and at great depth. And that means removing large quantities of fish through industrial fishing could have important consequences for climate change. It isn't easy measuring it or modelling it, though.
