> Even over a population center, it’s a local problem.

Local? An impact in any large city with financial or industrial hubs would have global scale effects. NYC, Tokio, Shenzhen, London, Beijing, Shanghai. Throw a rock at any of those and the world will devolve into chaos.

Yeah, but most cities aren't global commerce centers, and the ones that are take up relatively little area compared to the total planet.

We could lose most of the cities on earth with largely local impact. NYC would be a problem, but what about Buffalo? Even most national capitals aren't that important globally.
