One of the advantages to using genetically modified organisms (GMOs) is

• reduce the need for pesticides

• they are not regulated by the government

• the concern about safety to consume

• they can cause food allergies

Monocropping has a number of disadvantages. These include all of the following EXCEPT

• Erosion due to exposure of large areas of soil during planting.

• Nutrition and pesticide needs should be similar throughout a single crop.

• Pests are likely to attack a monocrop due to the high concentration.

• Loss of habitat for natural pest predators.
