Drain the Ocean

"Three-quarters of Earth is an alien world, lying beneath the surface of the oceans. And although it encompasses over half of the world's species, we know more about the surface of Mars than the bottom of the ocean. It's only recently that science has penetrated this world, revealing extraordinary life forms and vast sweeping landscapes on a scale that defies imagination"--Container.

Plate Tectonics [electronic resource]: Secrets of the Deep

Viewed from space, one of the remarkable features of our planet is that it has continents and oceans. The changing pattern of the continents and oceans is a very important characteristic of the earth, and the discovery of how this movement occurs is one of the most exciting scientific stories of modern times. The key to this understanding lay not in the continents at all, but in the oceans. The oceans turned out to have a record of their history as precise as tree rings or a magnetic bar code, and with it came the history of relative motion between the continents. These motions are not fast by our standards, but by geological standards they are very rapid. As a description of what is happening in the oceans, plate tectonics is so simple, powerful, and accurate that it has come to dom [...]

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.

MyPlate [electronic resource]: Understanding the USDA Dietary Guidelines for Americans

When the USDA replaced MyPyramid with MyPlate, the goal was to simplify dietary recommendations by providing at-a-glance guidelines without having to weigh and measure at every meal. This program explores the key concepts of MyPlate and how it correlates to the more detailed Dietary Guidelines for Americans, including portion sizes, proportions, food group choices, and caloric balance. The video explains why it's a good idea to fill half your plate with produce, and even breaks down which vegetables edge out others in terms of fiber and nutrients. Stressing the impact of poor eating habits on health, it discusses fat and salt intake, high-fructose corn syrup and other sugars, and whole versus refined and enriched grains - and suggests seafood and other protein choices beyond just mea [...]

My City, Your City [electronic resource]: A Senegalese Mayor Fights Sea Level Rise

During the annual rainy season in Saint-Louis, one of Senegal's largest cities, thousands of people face upheaval from flood devastation linked to rising sea levels. There are no funds to build a cement sea wall, so the city dumps garbage along its waterfront in an attempt to shield itself. As mayor, Cheikh Bamba Dieye took on the responsibility of protecting his constituents from flooding, but with a severe lack of financial and infrastructural resources, the world stage became his principal weapon. Filmed prior to his appointment as Minister of Regional Planning in Senegal's national government, this program follows Mayor Dieye as he visits the imperiled streets, structures, and beaches of his city and as he travels to Mexico City to address the World Mayors Summit on Climate Chang [...]

The Day the Wave Came [electronic resource]: The Tsunami Disaster

The world is still coming to terms with the magnitude and impact of the tsunami that decimated the coastline around the Indian Ocean on December 26, 2004. This documentary introduces newspaper reporter Ross Coulthart, who traveled across the region soon after the tragedy occurred to record the survivors' stories. He provides a minute-by-minute account of what happened in countries most affected by the disaster. The Day the Wave Came is a comprehensive retelling of how events unfolded. Why no warnings were issued is explained, and the individual stories of how people survived and what the impact has been on their shattered lives are retold.

The Blue Planet [electronic resource]

Presents new revelations about the oceans, the last unexplored frontier on earth, from space by scientists aboard the space shuttle and by scientists diving to the depths of the middle ocean to examine rare life forms. Covers cycles of weather, aquatic weather, the Gulf Stream, concentrations of plankton and coral reefs. Introduces technological innovations that are used in studying the ocean and its creatures.

The Last Drop [electronic resource]: Is the World Running Out of Water?

Water shortages contribute to many regional conflicts worldwide. Only two-and-a-half percent is fresh, and it is therefore a precious commodity. This documentary illustrates how the worsening problem of global water shortage leads to regional political and social conflicts, destruction of economies, and famine. Beginning in the Middle East, we see how diversion of water to Israel at the expense of Palestinian villages has exacerbated that conflict. In Namibia, in South Africa, cultures are dying and people are starving, as hydro-cops monitor water use and abuse by residents. Experts predict that countries along the Rhine may find themselves in the same dry situation, if water diversion from the river continues at current rates. Throughout the program, experts, those involved in water [...]

Waste Disposal [electronic resource]

Household waste can cause pollution of all kinds, but more and more of these wastes can be recycled effectively and economically. The result is reduced pollution and a useful new source of raw materials and energy. Hospital waste disposal presents the additional problems of contaminated waste, which is a series of problems depending on the nature of the waste: contaminated blood waste, for example, requires different treatment from radioactive waste. Finally, there is animal waste, which is natural enough but nevertheless the cause of pollution if it is not properly treated. The program also shows how pig waste is treated.
