A cooled climate led to deaths of livestock and changed fish patterns in New England, leaving many people dependent on the mackerel, an edible fish that was less affected than many animals. The researchers assert that bit of history gives clues about what food security could be like in the modern era of climate change. How fisheries in the developing world will adapt to future climate change is an important contemporary food security issue, because fish are a vitally important protein resource worldwide. More than a billion of the world’s poor obtain most of their animal protein from fish, and 800 million depend on fisheries and aquaculture for livelihoods, according to the nonprofit research group WorldFish.
