In the "Three body problem" one of the main themes is an alien invasion and threat to the entire planet earth. As part of humanities plan to come up with solutions is the idea that any person or company found to be working on any technologies or plans to escape this planet is commiting a crime against the entirety of humanity and are charged accordingly. With the idea being that any effort going towards escape takes away from humanities effort to combat the threat.

Anyways since I read that I've wondered what it would be like if we treated the threat of climate change that way.
