52 Hertz: The Loneliest Whale in the World 
It's fascinating! Though it's interesting to debate if we should apply humanly qualities such as loneliness to whales (or even other creatures). Does this whale really feel lonely (like we do)? Or is it just doing what its genetic program tells it to do? I don't recall where exactly I read, but I had read that the contribution of language is significant as far as human consciousness and feelings are concerned. It mentioned that animals have signals as a form of communication (show a ball, and dog would come over) but humans have signs. The whole conscious world is composed of signs for us and that is what makes us unique. It had further mentioned that even in aboriginal people who don't know much about modern cosmology, they still have a theory of some sort to signify the origin of world. Animals simply lack that kind of framework and therefore behave according to their genetic program or trainings.Yes, the field was called semiotics and I recall reading about how a wandering bee doesn't give a damn to humans dancing and celebrating nearby.
