This 4-part, 3-hour documentary from CBC's "The Nature of Things", narrated by David Suzuki, follows the investigations of several scientists around the globe as they make new discoveries about the state of the oceans. The third part, "Mysteries of the Deep", is the most beautiful and spectacular, but the whole series conveys the sense of wonder and excitement which motivates these inquirers. However, the amazement is tempered by a growing sense of concern, as they are also discovering the many ways in which human activities (such as overfishing and excessive carbon dioxide emissions) are threatening the very cradle of life on this planet.
Part 1 explains how the oceans were formed and enabled life to emerge and evolve. Part 2 examines some conservation practices which, if implemented widely enough, would halt the destruction of ocean habitat and enable us to sustain a healthy relationship with the oceans. Part 4 documents the massive changes now taking place in the oceans, including "dead zones" and acidification, because we either don't understand the oceans well enough or aren't using what we do know to implement sustainable practices. In other words, we aren't taking responsibility for the quality of our own future.
The oceans, like the rest of the biosphere, will take care of themselves as they have for over 4 billion years -- but their response to the relatively sudden stress we are putting on them will disregard our welfare just as much as we disregard the welfare of our fellow beings on this watery planet. If we fail to pay due attention to the wonderful web of life that sustains us, it's likely to shrug us off as a failed experiment. This series shows why, and that makes it a must-see.
