I agree about making limestone; see #114.

A series of clever, interlocking initiatives could make a profound difference. The basalt you mentioned can be melted and extruded into fibers with less embodied energy than fiberglass or carbon fiber. Then that is used to build electric airliners and for reinforcement in concrete buildings.

Ice Ages reduce the available land area, but they also do push diseases back to the Tropics.
