Well, most of us don't have a plan B if the Earth is wrecked by pollution, but I guess if you beg Musk hard enough, he might invite you to Mars.

We can either do drastic things now, or desperate things later.

Hyperbole like that doesn't help anyone.

Pollution and environmental destruction are big problems, but there are no remotely likely scenarios where the Earth "is wrecked by pollution" and a HN reader would need to question the viability of remaining on the planet.
