The Park Service movie series at the Kenai Fjords National Park got on its soapbox a couple times. They played a couple wonderfully thought provoking PSAs: “Ocean Symphony” with Jack Black and “Tiny Fish”. They can be viewed on shiftingbaselines.org  The premise: we fail to notice as the world around us gradually changes. The main focus is changes in the seas and their goal to create more Marine Protected Areas and educate to defend the ones we have. It started in 2002 as The Shifting Baselines Ocean Media Project. I’m going to need to learn more about it.
