"Yellowstone explodes roughly every 600,000 years, and it is about 600,000 years since it last exploded, which should cause us to sit up and take notice.”
We get hit by a devastating astroid once every hundred million years. It’s been sixty-five million years since the astroid that killed the dinosaurs hit us. Astrophysicists are urging us to develop self sufficient colonies on another planet, probably Mars, so it will double humanity’s chances for survival. There are other things that could destroy us too. I think there is a certain type of solar flare that could fry all the electric grid worldwide, sending us back to the stone age, with massive loss of life. There are other similar threats. The space program isn’t about satisfying some curiosity among useless old men. It’s about keeping civilization going through the many hazards to life on earth. There has never been a time of more abundance on earth. We need to get our allies to take more responsibility for our mutual defense, and put these technicians to work on a much more ambitious space program.
This is one of the most thoughtful, well-reasoned responses I’ve seen on here.

Would this volcano really cause extinction?
it’s a good question, cause the last times it has erupted, it didn’t cause our ancestors to go extinct. and nowadays, humans have the benefit of technology. it’s safe to say that it would wipe out a large portion of our species, though.
