Elon Musk: Earth only has about 10% of its lifespan left before becoming uninhabitable.

“If Earth has been around for 4.5 billion years, which is what the fossil record suggests, then Earth only has about 10% more life in it before it gets so hot that life is impossible.

It's not about just landing on Mars and doing flags and footprints. It's about creating a self-sustaining city on Mars with the fundamental fork in the road of destiny being that Mars is sufficiently self-sustaining and can grow by itself. If the resupply ships from Earth stop coming for any reason, whether that is because civilization died with a bang or a whimper, but if the resupply ships are necessary for Mars to survive, then we have not created life insurance, we've not created life insurance for life collectively.

That's the key point in the future where destiny of life as we know it will forever be affected is when Mars becomes self-sustaining.”
