Do you know where your food comes from? To find out, acclaimed photojournalist George Steinmetz spent a decade traveling to over 30 countries and 24 US states documenting global food systems. In striking aerial photographs, he captures the awesome scale of 21st-century agriculture that has sculpted 40 percent of the Earth's landmass. He explores the farming of staples like wheat and rice, the cultivation of vegetables and fruits, fishing and aquaculture, and meat production, in situations ranging from traditional farms in diverse cultures to vast agribusinesses, on every continent except Antarctica.
