Feel sorry for the fish. Feel even sorrier if you like seafood. Fish are under assault from two sources: climate change and overfishing. Fish consumption is up, which many doctors applaud, but fish populations are down. The sustainable yields are down as much as 34%. The populations may ‘only’ be down ~4%, but many are becoming unsustainable as the schools become too small. At the same time, climate change is changing, shrinking, and shifting their environments further decreasing their sustainability. As human population increases, and prosperity increases, meat consumption increases. With sea food under threat, and the environmental consequences of red meat production becoming better understood, changes in food habits and production will become necessary. The fish would probably appreciate some relief.
