We deserve to because we can. To continue life beyond what the planet us capable of sustaining is a kind of ultimate purpose to life. Building structure to live in instead of planets.
Humanity doesn't deserve to survive. If we are to live on other worlds, we must as a species be worthy of survival.
I'm not saying we shouldn't go to Mars, just that humanity needs to learn. We can't run away from our problems. The day will come when humanity will have to face what it has done.
Deserving to survive comes with being capable of surviving. It doesnt matter if we have to destroy the Earth to do it, just so long as we can leave the Earth.
It is of course an extreme case, but if it meant taking life beyond, and ensuring its future, then I would find it acceptable. I doubt that would be required though.
Allowed by who? I dont think you understand what I was saying. The people alive today are irrelevant to the issue as humanity isn't capable of this yet.
A major emergency I would guess. That or if climate change was set to destroy us. Building habitats that could hold ecosystems would take a lot of collective effort.
A major emergency like what? Climate change set to destroy us? You're referring to a major kind of catastrophe where we humans are forced to work together or die?
We live in a time of unprecedented connectivity on a global scale. To what I'm aware of - and you? - this has never before been the case. There's only one problem: our own minds.
There's only one thing that's needed - a systematically voluntary society. Since maintaining slavery is directly opposed to this, this very simple thing has become very complex.
It's actually quite simple. That doesn't mean it might not be very complex in practice, although anchored on a basic idea. Like BCH - decentralized digital cash.
