More land, some 11.5 billion acres, is under cultivation than at any other time in human history. More crops—in 2020, total agricultural output was worth about $8 trillion—are in production than any time in human history. That’s roughly 10 percent of global GDP, the largest value of any economic sector. More of those foods, over one-third by value, are internationally traded than at any other time in human history.
