Given the devastating impact of overfishing, Earle may have a point. As Jane Brody noted in the New York Times recently, even if we shift our focus to more resilient wild species, the demand for fish is growing so fast worldwide that we will still need to find alternatives to fishing for sourcing a large portion of our fish. With nutritionists advising us to eat more fish as a healthy alternative to meat, and with significant environmental concerns around land-based animal agriculture, is there any way for us to have our fishcake and eat it too?
