For me, there is no threshold. As I see it, it's going to take Q, the military, or some act of God to save this place. I'll of course do everything in my power to protect the ones I love, but we are frankly in no position to save the world. So, we might as well stay hopeful regardless of what we see in the news. There's no viable Plan B, or at least I certainly haven't seen one suggested that doesn't glow to high heaven.
