"When the next asteroid arrives, or when Cascadia slips, there's not a whole lot you can have done to make a difference." Asteroids can be diverted, given enough warning.[1] There are theoretical proposals for doing so, but its never been tried. Massive funding of testing, standby spacecraft with asteroid diversion capability, and increasing Earth's early warning system are all realistic things that could be done, were there a political will to do it. Unfortunately, like COVID, I expect it'll take a devastating asteroid impact that costs millions of lives and trillions of dollars before the Earth wakes up to this threat.
