An environmental benefit of some genetically engineered crops is that
a. they are easier to harvest.
b. they contain fewer common allergens.
c. they may be grown using fewer pesticides.
d. foods made from them have a longer shelf life.
C
Crops may be genetically engineered so that they produce their own natural pesticides that are harmful to insects but not to humans and animals; they therefore require use of fewer pesticides which is beneficial to the environment. Crops may also be genetically engineered to make them easier to harvest, to contain fewer common allergens, and to produce foods with a longer shelf life. However these effects would not have a direct benefit for the environment.
