While NASA and Elon Musk may disagree about the viability of terraforming Mars — that is, making it capable of supporting human life — we need to first ensure that this planet is habitable, and that the stability of human society is not drastically interrupted.
We need to terraform Earth, ensuring that its atmospheric greenhouse gas levels are within the range that has allowed humankind to flourish. I share the dreams of NASA when I look up into the night sky. But let’s work to save this planet first, and then go to Mars.
