This seems easy to say, but how can small groups of people make actionable change on burning less fossil fuel? Will you protest outside coal plants? Cement plants? Steel plants? Stop flying in airplanes? Do you still use a car that burns gasoline? Will oil companies do the right thing and simply choose to make less money?

I agree that not using fossil fuels is the most efficient method, but it's also not easy to take action on. We need to pursue every viable avenue in parallel, and carbon removal solutions are, if not particularly efficient yet, at least very actionable. And with R&D, perhaps they will become more efficient.
