What is One Concern with the Use of Genetically-Engineered,herbicide-Tolerant Crops

Question

What is one concern with the use of genetically-engineered,herbicide-tolerant crops?
A) decreased yields
B) potential allergic reactions
C) transfer of herbicide resistance to weeds
D) loss of genetic diversity
E) expense of using herbicides

Accepted Answer

The concern with genetically-engineered, herbicide-tolerant crops is that there is a risk of transfer of herbicide resistance to weeds. This could lead to the development of superweeds that cannot be controlled by herbicides, leading to a potential increase in the use of herbicides and the development of new herbicides.
