Not long after the
massive land dispossession that impacted most Indigenous tribes, industrial agriculture began to take over much of the country’s crop production. Though farmers were able to grow cheaper and more plentiful food, it came at a great cost to the environment, public health, and culture. It also came at a great cost to the seed supply.
Then, in 1980, the Bayh-Dole Act allowed companies to start patenting seeds. Those varieties often produced even higher yields but could only provide such results for a single generation of plants. This meant farmers now had to buy new seeds every year. These companies also sought to hook farmers on varieties that could withstand large amounts of dangerous pesticides and herbicides.
It worked. Chemical-laden monocultures took over, companies like Bayer and Monsanto expanded and merged—and the seed pool dramatically shrunk. By 2019, just four companies owned 60 percent of the world’s seed market. Most Americans today are accustomed to eating one type of corn, one kind of potato, and one color of carrot.
