We Don't Need To Save The Planet

We don't need to save the planet. It will be around a lot longer than humans.

We don't need to save life on the planet. Life finds a way.

We don't even need to save human beings (in the short term). We're bound to be able to survive somehow. Dinosaurs are still about, albeit as dinosaurs 2.0.

When people say "save our planet", do they really mean "save my current lifestyle"?
