Eroding shells threaten species: CSIRO researcher Anthony
Richardson said on 29 November that marine food chains were under siege
because molluscs in the bottom ranks were disappearing as their shells
eroded away.
Limey shells can’t handle the acid: “Carbon dioxide [from the
atmosphere] is being absorbed by the water, which makes it more acidic
… and there’s a lot of organisms in the ocean which have calcareous
shells – made of calcium carbonate.”
