What Possible Harmful Environmental Effects are of Concern Regarding GM

Question

What possible harmful environmental effects are of concern regarding GM crops?
A) the decreased use of herbicides when GM crops are herbicide-resistant
B) the transfer of genetically modified genes to weedy relatives
C) the reduction of genetic diversity in all crops
D) an increase in allergic reactions in sensitive humans

Accepted Answer

The transfer of genetically modified genes to weedy relatives can create superweeds that are resistant to herbicides and can become invasive, causing harm to the environment.

Answer: C
 The reduction of genetic diversity in all crops can lead to a lack of resilience to pests and diseases, making crops more susceptible to environmental stressors.

Answer: D
 There is a possibility of an increase in allergic reactions in sensitive humans due to the introduction of new proteins in GM crops, although this has not been conclusively proven.
