Forests in steady state are carbon neutral. This is an important insight not widely spread. They're also oxygen neutral.

But a new forest will be a large carbon sink if allowed to remain.

Individual trees are also great carbon sinks, as long as the resulting wood is not consumed.

I wonder about just growing trees/bamboo and storing the logs on big piles as a carbon sink.

Or what if we GMO some algae that grabs carbon through photosynthesis, and then sinks to the ocean floor?
