A developing country is considering approving the cultivation of genetically modified (GM) soybean with herbicide resistance and GM cotton with insect resistance, as well as importing GM salmon with enhanced growth rate. Proponents argue these will help meet the country's rising food demand. Critics raise ethical and social concerns. Using the examples given, explain how genetic engineering could help meet global food demand and discuss the ethical and social implications that must be considered.

Genetic technology: explain question
Explain5 marksChallenge
How this question is marked
5 marks, so the mark scheme is looking for about 5 separate creditworthy points. Making the same point twice in different words earns it once.
Explain means: Give the reasons or the mechanism: why or how something happens. Link each point to the next with because, so or which means. A list of facts with no links usually loses the reasoning marks.
