I wonder what would happen if there were a world-wide campaign to plant fast-growing weeds such as hemp? If literally everyone who had access to sunlight and water did it, you might be able to collect enough carbon to make a dent. then you'd have to put them somewhere. I imagine the dried plants could be baled and stored underground. They would still release some CO2 from oxidation but perhaps theres a way to stop that ?
