Man is alone in the universe. - "The Long Loneliness"

Mankind, it seems, is alone in the universe. We as the human race think we are alone with our level of intellect. We cannot dream of interacting with other animals the way we do with other individuals of our society. Of course it is always possible that we as humans may not be aware of such occurences in nature, but nevertheless, whether we are unable to communicate with animal because they have a higher intellect or whether we think we are too smart that simple dogs cannot dream of communicating with us, it is true that the only friends we have as of right now are other humans.
Although many think that this may be the case, I beg to differ. Humans are far from alone in this universe. If we simply look around we see the many wonders of nature around us. The plants and animals and human all live in harmony. As you get further into nature, you see all the ecology around you looks like it is the part of a puzzle. Humans are alone in the sense that we are smarter; yes. But never can we say that we are alone with our little selves in this whole universe. Our planet is filled with wonders of nature where everything works in an orderly fashion.
Humans however are alone once again because we are the ones who destroy this beautiful balance. While growing apart from nature, we have left our sense of preserving the nature along with our ancestors. We upset the balance, and surely enough if we don't stop doing so, one day we WILL be alone on this planet. Imagine what that will be like.
No, we are not alone in this universe. Nature takes care of us. We should return the favor.
