It has had a dramatic change on me. I cringe at the urban sprawl I now see, whereas before I called it "progress". I now hunt with a camera instead of a gun. Even though I'm not against hunting, I simply no longer have the desire to do so myself. I don't kill animals that I perceive as a "nuisance", I now understand their part in the world. I now pay attention to the political candidates views on the environment, and will not vote for candidates that do not show concern for the destruction of habitat. I could care less about TV or the news. I'd rather be out in some swamp with my camera. My wife has noticed the change as well.
