You've also asked the aerospace industry to come up with evacuation ships, in case we need to abandon our planet. You know my opinion on the feasibility of that. We could, at best, "save" a few hundred thousand people. Those people would have the "privilege" of dying in space of starvation or radiation poisoning, rather than dying of starvation on Earth, or being consumed by the Black Tide. After the last several decades of decreasing space budgets, we simply don't have the know-how to build sustainable space stations. Certainly not self-sustainable space stations capable of supporting thousands upon thousands of people.
