While it's difficult to envisage the situation in 100 years or so, right now the third option seems the most stupid. It's like giving up without the fight. We have this wonderful green-blue planet rich with resources and able to provide everything we need. Leaving it and looking for something better or even equally nice - I don't know how realistic this is. What we really need is a global plan for dealing with the issues causing most damage. The "start with the 10 top polluting power plants" is a good starting point, we need more. When we act together, we can produce marvelous things quickly, as the example of COVID-19 vaccines show. I'm all in for exploring space, but it's not our way out for now.
