In a previous blog post, I referenced a quote by Stuart Hameroff about the nature of consciousness. In the following video, Hameroff and Deepak Chopra discuss this topic in greater detail.
An important point is that consciousness does not arise at a certain level of complexity but is embedded into the very fabric of the universe itself. This point of view can help us realize the oneness we share with the world around us. (As differentiated entities in nature, some are more complex than others, some are more aware than others, but none are "better" than others; that would be like saying an organism is better than a cell).
Another important point is that humaness (i.e. consciousness) cannot be reduced to simple bio-chemical processes in the brain. Consciousness is not just a product of neurons in our brain acting as on-off switches, which, at a certain point of complexity create consciousness. (As a side note: the de-humanizing effect of this view point in the world of technology is the topic of a good book by Jaron Lanier called You Are Not a Gadget.)
Here's the video:
