Colonizing other planets is not a solution. It is vastly harder to terraform Mars than to repair the damage we've done to Earth. Multiple technological Holy Grails must be discovered in order to make it even remotely possible. Not happening.
A colony established on Mars with current technology would be completely dependent on Earth for food and other supplies.
If we've passed the red line already, then it's all over and we may as well live it up while we still can.
I didn't say terraform.
Then why bring up other planets? Even if the worst global-warming predictions come true, Earth will still be vastly more hospitable than an unterraformed Mars, and all of the other planetoids we can reach in a single human lifetime are even less fit for human habitation.
Until and unless somebody invents either the warp drive or the means to terraform Mars, we've only got one planet to work with. If we trash it, that's it—game over for humanity.
