Your talk of plants reminds me of that Quote Paraphrase " When will science advance to where nature has been all along"
As we know CO2 is constantly absorbed, but not in the Rain forest as most people think , but in the oceans by little folks in the plankton world which out number Photo cells on terra by 200 to one. Want to absorb more CO2 , Aid Planktonic life, stop polluting Oceans. I know , never happen.
