This is also good for climate change. Concrete is filthy, carbon-wise. Probably the ideal built-form, sustainability-wise, would be something like Paris or Milan, but made of wood. Like a 5-8 storey streetwall of wooden multi-unit homes (whether apartments or stacked townhomes or whatever), dense-enough that it can be serviced with higher-order transit but no so dense that concrete construction is required for the buildings.
