Maybe it is time to hand over the stewardship of the planet to another species? Would they do a better job than us? After all, the dinosaurs probably thought they were top of the food chain until they weren’t. And they had managed to last for 180 odd Million years.
I agree with several of the above posters that talked about the cyclical nature of these events, and can’t help thinking mass extinctions are part of that cycle. I just hope we get our act together and make sure we don’t go the way of the dinosaurs.
