Energy and Resources [electronic resource]

As the Earth's fossil fuel reserves decline, what forms of energy will come next? After discussing the formation, uses, and consequences of burning coal, oil, and natural gas, this video explores the development of alternative resources that may someday completely replace them: nuclear power, solar energy, biomass, geothermal energy, hydroelectric power, and wind power. Benefits, costs, and environmental impacts are considered.

Energy Security [electronic resource]: India's Sustainable Solutions

In India a new generation is enjoying the luxury of air conditioning, not just at home, but in the thousands of commercial buildings that have sprung up in the flourishing economy. With its increased energy needs India is now spewing more greenhouse gases than almost every other country-and yet there still isn't enough electricity to meet the demand. This program examines India's energy shortage and the sustainable alternatives being employed to address it. Wind turbines have been effective in Tamil Nadu, and in Karnataka, villagers using fuel made from cow dung find benefits beyond the ecological: their health, finances, and educational opportunities have all improved.

Rain Forest [electronic resource]

The tropical rain forests of the world are home to nearly half the animal species on earth and contain some of the most fascinating examples of natural adaptation ever seen. This classic program takes viewers into the rain forests of Costa Rica to witness a richly varied habitat under threat from human encroachment. Here, a basilisk lizard walks on water, howler monkeys bask in the sun, and leaf-cutting ants carry sections of foliage many times their weight into underground fungus gardens. Still provocative after a quarter century, the film sounds an eloquent warning about the natural wonders we stand to lose if industry and agriculture continue to take precedence over rain forest protection.

Water [electronic resource]: A Celebration

Nothing is so familiar, and yet so elusive, as water. A running faucet would require 136 trillion years to discharge the Earth's 326 million cubic miles of water, but only fresh water-less than three percent of the global supply-can sustain life. As we transport, utilize, and consume water, we are tempted to view it as eternally plentiful. But its protracted cycle of falling from the sky, seeping into the ground, resurfacing, and evaporating is a fickle, unwieldy process that makes water more precious than gold. This program investigates the uses and meaning of water in our lives.

United Arab Emirates [electronic resource]: Oil and Water Resources

The UAE's oil is plentiful and readily consumed by an energy-thirsty world; meanwhile, the nation struggles with its own thirst for water. This program documents the history of the wealthy Arab nation and how it deals with water scarcity and an abundance of petroleum. Detailed discussions of the oil drilling and seawater desalinization processes, conversations with young UAE citizens, and a stroll through a souk, or public market, vividly illustrate cultural and economic aspects of this Persian Gulf country.

Peak Oil? [electronic resource]

Peak oil: the point at which oil-producing countries, faced with diminishing crude reserves, can no longer keep pace with growing demand. Has the world already reached it, or is the point of irrevocable decline still decades away? That is the slippery question that frames the narrative of this program as experts from around the world give their views on factors associated with escalating oil concerns: soaring global demand, market speculation, lack of timely upgrades to oil-refining production chains, political turmoil in oil-producing countries, rising costs to explore and tap remote oil fields, and the global oil supply itself, an unknown-and, in the case of Saudi Arabia, an undisclosed-quantity. Although deep-sea drilling and fuel from tar sands, liquefied coal, ethanol, and biodi [...]

Going Green [electronic resource]: Real-World Solutions for the Environment

It's easy to talk about environmental stewardship, but quite another matter to practice it. This compilation of 12 ABC News stories shows how governments, businesses, and individuals around the world are taking concrete, eco-friendly action. Each engaging example of "going green" offers an opportunity for class discussion, further study, and perhaps even genuine change.
