@zens@merveilles.town That depends heavily on what you mean with "natural". Obviously, "do nothing and let nature sort itself out" isn't gonna be a solution, but that doesn't automatically mean that mechanisms like algae cannot be sufficient when deliberately/strategically applied.

Assuming that we must need to invent some futuristic technology (which does not exist yet and therefore we cannot actually apply today) is, to me, just the other end of the "appeal to nature" fallacy.

Maybe the answer *does* turn out to be that algae (and other "natural" forms of carbon capture) cannot be sufficient. But that should be verified and supported with evidence/numbers, not just assumed and preemptively excluded as an option!

Otherwise we'll just end up doing nothing and waiting for some hypothetical future technology to arrive (that maybe never will), all the while the problem gets worse.
