Missing Polar Bears
We were watching an ABC news special about earth's future, and one of the kids in the room bemoaned the fact that at some point we may no longer be able to see polar bears. We'll miss them! But wait--we weren't going to see them anyway. How many people visit the fringe of the arctic, where they live? In the future, we'll still have all the images and videos that we do now. What we'll no longer get to have is a certain thought--that there are polar bears living up there in the arctic. Curiously, that will change the look of pictures like the one above. They'll no longer represent (roughly) polar bears in our world, but a past we can't retrieve. Oddly, what you think while viewing a picture affects the way the picture looks.
