A fundamental fact should have stopped the original publication in its tracks: The organic carbon in oyster biomass is not mCDR.
We eat it, use it, and exhale most of it as CO2. That's what animals do — organic carbon in, carbon dioxide out. What we don't use goes to sewage —> greenhouse gases.
Gentle people:
The challenges in PNAS to a seriously flawed study of oyster farming for carbon dioxide removal are completely valid. The reply by the study's authors does not address core issues. To...
