A region has 800 hectares of land available for growing sorghum. The population of the region is rising.
Scientists compared a GM variety of sorghum with a non-GM variety. Each variety was grown on a different area of land for one year.
| Variety | Area planted in hectares | Mass of grain harvested in tonnes |
|---|---|---|
| Non-GM | 2.0 | 12.4 |
| GM | 1.5 | 11.1 |
Use the data to calculate how much extra grain the region could produce each year by growing the GM variety on all 800 hectares instead of the non-GM variety.
Explain how this change could affect food security in the region.
