Since 1994, when the first commercially grown GMO plant approved for human consumption was introduced—a slow-ripening tomato variant known as the Flavr Savr—well over fifty GMO crops have been developed and approved for commercial cultivation in the United States, among them canola, corn, cotton, papaya, rice, soybean, squash, and many more. In 2015, 92 percent of all corn, 94 percent of all cotton, and 94 percent of all soybeans grown in the United States were genetically engineered in this way.
