When we kill that which sustains us, what will be do?

Bioengineer the planet? I haven't heard that's been successful in small closed systems. Want them to try globally if they fail smaller scale? It's a stupid risk.
Terraform Mars is a joke. 100,000-200,000 years with current technology and one solar flare would wipe our surface inhabitants and rip the atmosphere away without a magnetic field to protect the planet.
Go to another star? Nearly 50,000 years to get to the closest at 4.3ly and even if we achieve 10% of the speed of light its still close to 50 years, one way. What if we get there and the planet is not habitable? 50,000 years back using conventional rockets which means, not coming back.

We have one place to live. The ultimate spaceship travelling through the cosmos. Absolutely perfect for human life and sustainable of we could get out collective heads out of our asses. Everything else is pure science fiction. Ludicrous some of our brightest minds suggest such things. The cost alone to achieve a fraction, if we're lucky of what we already have? I question the logic of it.
