Sure, but if we don’t need all the land we’re currently using for parking, we can build a lot of new infill mixed-use housing that’s built of fast growth biomass materials (compressed laminated timber, bamboo, pine, hemp) that are all sequestering carbon while lowering the average person’s carbon footprint. Figure out mass adoption of plant, fermented, or lab-grown protein, and we’re well on our way to tackling climate change.

I figure this buys us enough time to get to orbital solar-based energy with panels made largely from materials mined on the moon.
