A manufacturer makes floorboards using timber from a managed plantation.
The manufacturer is choosing between two production plans. The predicted annual resource use for each plan is shown in the table.
| Resource information | Plan A | Plan B |
|---|---|---|
| Timber harvested in tonnes per year | 24 000 | 34 000 |
| Timber regrown in tonnes per year | 30 000 | 30 000 |
| Natural gas used in GJ per year | 18 000 | 6 000 |
Explain which plan the manufacturer should choose for more sustainable use of resources.
Use the data in the table and your knowledge of resources.
