I personally would vote in favor of putting space exploration on hold until we get a handle on the quickly accelerating environmental disaster we humans have set up that seems that it may just wipe ourselves out.

Personally.

One needs beauty in the world, yes, but one also needs to breathe.

This doesn't make any sense though, as there's no reason they should be exclusive priorities. I, personally, would vote in favor of putting many things on hold until we increase humanity's resilience to catastrophic events by settling on other planets, but I recognize that priorities aren't mutually exclusive.

Anyway, what's the point of focusing all efforts on Earth if human civilization is going to die out here anyway? That's the path we're currently on, and stopping space exploration isn't going to magically fix that. Wanting other baskets for the egg of human civilization is just pragmatism.

Environmentalists will never be satisfied. There is always something to improve.

If humanity dies or goes pre-industrial because someone engineered a supervirus and we refused to put effort into space travel, all our conservation efforts won't really matter much.
