If you are interested in climate issues and renewable tech, then some aspects of the "Great Filter" concept [0] are probably in mind, especially those having to do with "Global Catastrophic Risk," [1] of which climate change is one. Others include events sourced outside the Earth such as a large asteroid strike or a large solar flare. These are events of unknown likelihood and vast impact. A space program is insurance against that in that humans might have warning or be able to do something about it one day. No space program means we are on borrowed time.

And I don't double that space programs do not create insurance against such. But from the articles I see, the target is Mars, not stopping an asteroid hitting the planet.

However, thank you the further resources on such.
