If you wanted to mitigate excessive atmospheric carbon, use bio carbon capture and sequestration. And where's the most logical place to do that? The ocean, as either phytoplankton or kelp or both.
If it were possible to regenerate this forest, who should get the money? Is there a way that the ecosystem itself could have a trust to ensure it’s long term ecological viability?

(I'm fully aware carbon credits are nonsense).
