What beneficial impact could genetically engineered crops have on society?

• They increase genetic variation in crops.

• They could create more efficient production, as crops could be altered to need no light.

• They decrease food allergies from crops.

• They could create a more stable food supply, as crops could be altered to resist droughts.

NGSS.HS-LS3-1

A gene found in naturally occurring soil bacterium, Bacillus thuringiensis (Bt), contains a protein that kills certain insects. Scientists have genetically modified certain organisms such as corn, potatoes, and cotton by introducing the Bt gene into their DNA in order for these plants to have this desired trait. Which describes a benefit of this technology?

• Farmers can produce more nutritional crops.

• Farmers can use less insecticides on their crops.

• Farmers can reduce the amount of fertilizers they apply to the soil for their crops.

• Farmers can reduce the amount of land needed to grow their crops.
