Articles like “We will never be able to live on another planet. Here’s why” highlight an important tension. As a fan of science fiction, I’m really excited by the prospect of space exploration and agree that, eventually, we need to find additional places to live and thrive.
Astronomical observations and Earth’s geological record are clear: the only planet that can support us is the one we evolved with. There is no plan B. There is no planet B. Our future is here, and it doesn’t have to mean we’re doomed.
And, so, we need to take much better care of our planet. There’s lots of excitement here too: clean energy, resilient infrastructure, better agriculture. Along with some real existential dread and disapointment with our behaviour so far.
I like to think we can do both of these things: explore beyond our planet, while taking good care of what we have. Sometimes the balance seems off though.
