Its not exactly on-topic, but i had an odd idea last night:
Surface mining (like for coal) pits are often filled with water after use. Would turning them into a dead zone/a bog be sensible to sequester carbon? Could we do the same to larger seas? This could also create peat or brown coal for future generations.
Is that a bad idea? And why?
- NohatCoder 4y agoCost and difficulty versus capture gains probably makes this unfeasible. Making a bog where no bog occurs naturally could be practically impossible.
