The link does snot help by itself. Could you elaborate what you think is relevant about that or how that applies?
Are you saying nature is not a perfect subject to model? I'm not sure what your point is, but I was a Phil. minor once, so I'll bite.

The argument you're making against carbon dosing above I think falls into this category and would be a fallacy. A filtration mechanism's existence or non existence in nature alone plays no role in whether or not it ought to be used in our systems.
Thanks for the input, I do appreciate a skeptic to keep everyone honest
