Seaweed Carbon Claims Overstated

PerthNobody issues a debit for lost kelp.

With 60% of kelp forests declining, they may soon emit more carbon than absorbed.

Carbon only counts as removed if it sinks to the deep sea; farmed seaweed mostly decomposes at the surface.

Marine ecologist Karen Filbee-Dexter says the priority is preserving kelp forests, not growing new ones.
