Now that the toxin is within the plant, each insect that bites the plant is exposed to the toxin. To safeguard against widespread resistance and these super pests, refuges have been proposed. A refuge is an area set aside as a haven for insects or weeds to grow and reproduce normally. These normal insects can then reproduce with the resistance insects with the hope that the normal genes will cover the resistant genes to produce nonresistant organisms. Another concern is that there are few laws to enforce resistance management plans.
Some companies do have plans required in their permits to sell genetically engineered seeds.
The question is how much monitoring is being done to ensure these plans are being carried out. This eliminates or reduces the use of toxic pesticides and herbicides which makes not only the air, water, and land cleaner, but also the crops themselves healthier. It is true that the problem of resistance results from traditional methods, but it is important to note that the insertion a control mechanism into a plant itself could make the spread of resistance more prominent. In addition to increased resistance, genetically engineered crops could also upset the natural balance of an ecosystem in several ways. One way includes damaging plant and animal wildlife, perhaps even causing some species to become extinct.
