Scientists working with Nikki Lovenduski write: "As scientists who study the global marine fishery, we are particularly interested in the future supply of seafood. So when some colleagues approached us with the idea of studying the response of the global fishery to nuclear war, we thought it would be a fascinating, though grim topic. As expected, our research showed that nuclear war would have a negative impact on marine fish, although not as bad as we had initially thought. Surprisingly, we also found that marine fish could serve as a crucial global emergency food supply in times of crisis if marine ecosystems were in a healthy state to start with."
