There are an estimated 2.1 million farmers in the USA and a further 293,925 in Canada. Estimates place the adoption of GM varieties of canola, corn, cotton and soybeans in the 90 percent range, in both countries. Given that many farmers in the USA grow either corn or soybeans, or both, 90 percent is a number that commonly used by the ag industry to refer to the percentage of American farmers using GM crops. In Canada, 97 percent of canola is GM, while 100 percent of corn is GM and about 80 percent of soy production, so a comparable figure of 90 percent is reasonable there as well. Based on this, over 2.07 million of 2.3 million farmers in North America produce GM crops on a yearly basis.
