We need to save our biosphere, now, immediately, this instant, from the devastation we are inflicting on it.

Musk's plans of a colony on Mars - which would take a century and quadrillions of dollars - are in direct opposition to this goal.

Spare me the "Who knows what new discoveries we will make through interplanetary exploration?" line. It's like buying lottery tickets because you're about to be evicted.

Unless we prioritize reversing the oncoming climate catastrophe, we won't get to Mars or anywhere else - our civilization will expire miserably in its own excrement here on Earth.
