We Have the Power to Destroy Ourselves

We’ve survived 200,000 years so far—2000 centuries. There’ve been risks during that time, most famously of asteroids hitting the Earth, as seems to have happened 65 million years ago when the dinosaurs were wiped out. That’s one type of risk we’ve been exposed to that whole time. There are also comets, supervolcanoes, like the Toba eruption, and risks of natural pandemics. These things have been around for 2000 centuries. The good news is that in most cases, we know that those risks must be small, because if they were even 1% per century, it’s vanishingly unlikely that we would have survived for 2000 centuries. We know that the natural background of risk must be fairly safe. It’s the type of thing that lets species live for a million years on average… More here.
