As scientists have developed more productive crop varieties, farmers have switched from growing many traditional varieties to new high-yield varieties. For example, in India, the 10,000 varieties of rice once grown have been reduced to 10 major ones for most of the rice crop. Why is this practice of reducing the varieties of a crop dangerous? Question options: It makes the overall crop more susceptible to pests and/or disease. It reduces the variety of crops available for human diets. it requires a larger investment than small farmers can make it could reduce or cause the extinction of some predatory insects
