Corporations across the food system increasingly have the power, by virtue of their size, market domination, political connections, and deep pockets, to set prices, meddle with science, evade regulation, and write the rules to benefit themselves. "Big Ag" and "Big Food" are shorthand for a sprawling collection of giant, often multinational corporations that wield enormous market power throughout our food system. Some of these companies are household namesfor example, Tyson Foods, John Deere, and General Mills"while others are virtually unknown to consumers. Those lesser-known companies tend to operate up the supply chain, and include Bayer and Syngenta, which sell the seeds farmers need and the pesticides they've come to rely on, and Nutrien and CF Industries Holdings, which manufacture synthetic fertilizers. The consequences of extreme agriculture and food industry concentration ... include supply chain instability, unsafe working conditions and downward pressure on wages, and higher food prices for consumers. Some 40% of farmland nationally is owned, in ever-larger tracts, by absentee landlords who don't farm but rent to others (in the Corn Belt bullseye of Iowa, it's more than half). Billionaires, including Microsoft founder Bill Gates, are among the largest private owners of US farmland. And corporations and investment funds like Nuveen and Manulife are buying up farmland at a rate that should alarm you.
