Speaking of the environment, it appears that we can help protect wild plants and animals and that it can work. Personally, I think hubris is our biggest problem at the moment. We now (mostly) know that biodiversity is good for us but need to recognise that nature actually knows better than we do and our best tactic is to learn from it, rather than conquer it. I mean really - how can we expect to know better than 3.85 billion years of trial and error?
