Reply to comment by try_cannibalism in MIT team makes a case for direct carbon capture from seawater, not air by MotorDrive

Just to nitpick point 3; disregarding the helicopters and trucks, if the wood never biodegrades isn’t that permanent sequestration rather than just carbon neutral?

If you're making new forests our of desert, it could be considered permanent sequestration if you assume none of the biomass will biodegrade, be burned, harvested, or otherwise released.

If you harvested 100% of the biomass and locked it away in a non-biodegradable product, like concrete.

But 99% of the time, you're only replanting the forest that was cut last year, most of the biomass is wasted, and all the products are either immediately consumable or eventually break down (how many wood buildings/furniture products even last 100 years these days?)
