d.
All of the above

Answer 1

d. All of the above

- Transporting imported coal uses fuel (ships/trains/trucks) and produces air pollution and greenhouse gases.
- Shipping and handling can cause coal spills and runoff, polluting waterways.
- Relying on imported coal maintains use of fossil fuels; without imports, alternative (possibly cleaner or different) fuel methods would be used.
