I've always been impressed with how so many of his movies reflect this view, without being preachy about it. Look at Princess Mononoke, for example: there are several violently conflicting sides, and most of them can be described as good, even heroic.
Indeed, Princess Mononoke is one of the least preachy eco-movies ever made, although I have a feeling that its main focus is actually not on environmentalism but on conflict resolution. To quote Miyazaki (from memory, from an awesome documentary/backstage series about Mononoke), the film is to "illustrate adult ways of thinking about issues".
The impetus for posting these Miyazaki quotes was the movie watching streak I went on recently. I've covered all of his movies except Castle of Cagliostro. I also read the Nausicaa manga, and its ending sign...
