As exciting and fascinating as this is, I really hope life never becomes sutainable on Mars. <br><br>We shouldn't have to abandon and give up on Earth, choosing to just leave to another planet. We have the capacity to rebuild and protect our planet - I only hope world leaders will hop on that train,(reply>), Earth is amazing and ought to be preserved...but that doesn't mean we can't or shouldn't expand out into the planets, asteroids, and even eventually the stars...,(reply>), If we're to look beyond our lifetimes (and our great grandchildren's lifetimes), there's a lot of reasons this is important. We may not be able to preserve the Earth forever, so learning how to make other planets habitable and sustainable may one day (far, far from now, hopefully) be necessary for the future of our species.<br><br>Though, to be a lot more pessimistic (and realistic), this species is far more likely to destroy itself than it is the planet. From AI to nano terrorism to nuclear war, there are a lot of ways we can set off a chain that can't be undone that will result in our decimation.,(reply>), Just cos we fix Earth doesn't mean we can't also live on Mars.,(reply>), People living on mars doesn't mean people abandon Earth.,(reply>), Yes exactly.
