"There is nothing we need to invent to be able to start a permanent human presence outside near earth orbit.Transport. Life support. Communication. etc" It is not just about 'Transport. Life support. Communication. etc', its about the fuel efficiency, the ability of humans to sustain in space, the ability to have great volumes of food, devote great time and risk, engineering hardships, etc. "there are so many issues that need" attention on earth is another matter. Can you specify?
The destruction of the climate.
That's why we have to create a space colony and make multiple planets suitable for life. We cant depend on a single planet's climate, etc.
I agree but you will never get support without doing both. The proponents will be labelled as "rats trying to leave a sinking ship.
Off earth colonisation, despite the claims of some, will required 50-100 of continuous investment to become self sufficient. If the climate crisis is not addressed there will not be a nation state able to support it.
Yes, we have to (individually) contribute to stop climate change, but also should not be on a single planet's climate, etc.
Also - humanity can do multiple things at once. Fixing climate change is a political/tech issue, not a lack of resources issue.
If individuals realize and take actions to stop climate change, we are good to go for it.
