I don't think any other living things on this planet besides humans think like, "this is good for nature", or "we have to protect the earth."
Of course, they don't have a brain to think about such things. But, more importantly they are the nature and they don't need to think about that to be in it.
They can be pretty selfish and still be a part of it.
Nature usually takes care of itself without having somebody worrying about it unless humans step in and mess with it. The destructions happen but that's also a part of it.
Since when humans became outside of the cycle?
Maybe we still are part of it in different perspective.
It just that when people came up with the concept of nature, we weren't in it.
