When plants, especially crop plants. are genetically engineered they are completely uniform in all characteristics. They have no genetic diversity. If the crop should be attacked by pests that it has no defense for, all will be affected and perhaps die, and the crop would be totally worthless.

Loss of crop diversity and depletion of water resources were was the draw backs of green revolution in Indian agriculture.

Show him or her all the benefits to crop rotation. Better fertility, lower disease incidence, lower insect pressure, better soil tilth, and greater diversity make it a really good choice for any farmer.

Any annual, biennial, or perennial plant grown as a monoculture (one crop type grown together) or polyculture (multiple crop types grown together), to improve any number of conditions associated with sustainable agriculture. Cover crops are fundamental, sustainable tools used to manage soil fertility, soil quality, water, weeds (unwanted plants that limit crop production potential), pests (unwanted animals, usually insects, that limit crop production potential), diseases, and diversity and wildlife, in agroecosystems.
