So, in eons past, carbon was sequestered naturally via calcium carbonate (CaCO3) if I'm following your math we'd need 4B tons of Ca / yr to sequester that yes?

So, in eons past, carbon was sequestered naturally via calcium carbonate (CaCO3) if I'm following your math we'd need 4B tons of Ca / yr to sequester that yes? Of course, that's vastly more than we produce a year, but it is the 5th most abundant element. Could we scale up CaCO3 production to sequester carbon?
- ip26 6y agoMy mind wanders to farming calcifying zooplankton. I wonder how hard it is to remove them from the carbon cycle.
- wing-_-nuts 6y agoYou also have to consider that as the oceans absorb more co2, they become more acidic, making it harder for plankton to form shells and sequester carbon.
