Table 1 shows the average yield (tonnes per hectare) of a genetically modified (GM) insect-resistant cotton variety and a non-GM conventional cotton variety, grown under identical conditions over two growing seasons.
| Year | GM insect-resistant cotton yield (t/ha) | Non-GM cotton yield (t/ha) |
|---|---|---|
| 2021 | 3.2 | 2.1 |
| 2022 | 3.5 | 2.3 |
Use the data in Table 1, together with your knowledge of other examples of genetic modification (such as GM salmon and herbicide-resistant soybeans), to discuss:
• how genetic engineering may help meet global food demand by improving the quality and productivity of farmed animals and crop plants; • the ethical and social implications of using genetically modified organisms (GMOs) in food production.
