text: what r the disadvantages of large scale enhanced crops on the availibility of naturally grown ones? i have a report to do! help me get a good grade and 10 points will be yours! there are a lot more advantages than disadvantages, of course. crop rotation reduces considerably the risk of extinguishing the naturally grown individuals. these ones are important mostly to preserve technology, creating a small population where certain diseases and plagues can keep living naturally, don't mutate and become resistant to insecticides, herbicides, fungicides, etc. large crops provide purer fields of the same quality grain/oilseed and at a lot cheaper price so the 6.3 billion people in the world can eat. remember that, crop rotation, crop protection, and selected fertilization make sustainable agriculture.
