Too bad nobody was around to “save the dinosaurs”. Just about any paleontologist or geologist knows that “climate change” (a.k.a. global warming) did them in - via an asteroid impact. The climate has change dramatically up and down since polar bears evolved into what they are now. Several times in the geologic past, there were no ice caps. What did the poor cuddly creatures do then? That’s why we aren’t drilling for oil in the National Wildlife Refuge in Alaska, to save polar bears, and a few rare species of mosquito from extiction? Might as well try to stop continental drift too.
