There certainly can be a lot of things that we get to see on the internet that perhaps we really rather not see, but there is also a wonder of animal behavior videos that are incredible. When I think about the not so long ago debates about whether animals have a sense of self, can use tools, are problem solvers, have feelings.. well the internet has busted that wide open. If anyone has any doubt, they should really take a look.
Also, think about this: Just as some researchers are able to use google maps and google earth to find new sets of data, so too is new information lurking inside the millions of home videos that are loaded day in, day out to youtube. What can you drill down for?
