Which of the following is a potential environmental risk associated with genetically modified (GM) crops?
- Increased crop yield only
- Gene flow to wild relatives, development of resistant pests, and impacts on non-target organisms
- Reduced need for any management
- Universal acceptance by all farmers
Answer: Gene flow to wild relatives, development of resistant pests, and impacts on non-target organisms
While GM crops offer benefits, ecological concerns include biodiversity effects, resistance evolution, and socio-economic issues requiring careful assessment.
