The Pacific [electronic resource]: Biodiversity and the Protection of Coral Reefs

Virtually every reef system in the world is endangered, and the island nations of the South Pacific provide some of the most troubling examples. This program examines the uncertain future of tropical offshore ecosystems using the French collectivity of New Caledonia as a case study. Viewers accompany lagoon protection crew members as they patrol fragile marine reserves by boat; an itinerant researcher who describes frequent legal conflicts between tribal interests and environmental regulations; and outreach personnel working with Kanak and Melanesian leaders to reduce traditional hillside burns, which lead to high sediment levels in lagoons.

The Arctic Circle [electronic resource]: On Thin Ice

For thousands of years, the only threat to polar bears came from humans. Nothing has changed-except now it is fossil fuel consumption, not spears and guns, that pushes Ursus maritimus toward extinction. Depicting the hapless species as the proverbial canary in a coal mine, this program studies the intensifying impact of climate change on the Arctic region. Viewers learn how the entire Arctic food chain, from tiny zooplankton to the ringed seal to the mighty polar bear, is under stress from ice depletion-and how severe drops in sea-ice thickness are related to the alarming appearance of meltwater channels and crevasse-like pits across glaciers in Norway and Greenland. Animated views of these anomalies help illustrate what is happening to the frozen landscape.

Over-Exploiting the Oceans [electronic resource]: Dangers of Over-Fishing

How long will the biosphere tolerate exploitation of the oceans? Are local fishermen a doomed species? What can be done to reverse the decline of fish stocks around the planet? This program documents the environmental and socioeconomic costs of excessive fishing. The film contrasts ancient maritime practices-like those of Mauritania's Imragen fishermen and Djibouti's pearl divers and lobster hunters-with large-scale fishing off Africa's coasts. It also raises awareness of financial and political factors, such as the granting of monopolies to corporations and consortiums and the failure of international regulations to prevent illegal fishing. The harm caused by trawl and gill nets, as well as the risks and benefits of aquaculture, are crucial topics.

Plankton Planet [electronic resource]: Harmed by Humans

Plankton fills an essential niche in Earth's food chain and a vital role in the health of the planetary ecosystem. For several decades, however, a growing level of human impact on the biosphere has been increasingly modifying the age-old equilibrium of marine plankton. This program examines the broad implications of three major concerns: how the inadvertent transfer of invasive plankton species via ship ballast is negatively altering the biodiversity of plankton; how agricultural runoff and other pollutants are affecting plankton populations; and how rising sea temperatures due to global warming are facilitating the proliferation of toxic plankton species.
