> I'm curious what extinction events you're so sure humans are capable of preventing that haven't been directly caused by humans It's hard to say, but we may be able to pull off redirecting an asteroid and geoengineering might help offset the worst of some future crisis. Being able to do something from a technical standpoint and being able to actually do it when necessary are very different things though. We're already in the middle of a mass extinction event of our own making and I doubt we'll be able to repair all the harm we've done. Expecting humanity to solve the next one might be asking too much.
