From the deadliest catch to the wickedest tuna, fruit from the sea continues to redefine who and what we are today. High-protein, omega-rich seafood saved our species from its first threat of extinction, drove the Viking hordes, funded the American Revolution, gave hope to the Allies during two world wars, and increasingly fuels our brains and muscles today. Market fish like cod and tuna defined entire eras of history, but unsustainable practices are forcing us to redefine our commercial goals in the ocean. Current demand necessitates a sea change in our attitudes toward seafood. Increasingly, we look "off the eaten path," investigating ways to catch, eat and prepare what the sea gives us instead of creating unsustainable demands for a single species. Newly developed techniques of 3-D ocean farming of oysters, mussels and sea kelp not only sustain us but heal the oceans as well.
