I remember a quote in the avatar movie where Sulley said: they killed their mother and they will do the same here. Definitely, it looks like we are good at destroying. The planet is really suffering because of us. Human beings have caused more threats than good on Earth. Even dinosaurs were not so terrible. From forests to oceans, we destroy whatever we find. In a way, we do it because we want to survive. On the other hand, by destroying the planet, we destroy ourselves. We cannot survive the destruction of our home-world. We need to find a solution and fight for our planet. It is the only place where we can live.
