For nearly all of human history, people have been hunter-gatherers. Agriculture has been a very recent development. On land, domestication dominates our food system—cows, chickens, pigs, and vegetables that we have greatly changed from their wild progenitors.

For a wild-fish lover like me—and likely you, too—this passing of an ancient era may be a little disappointing.
