Tells the inconvenient truth about the environment. Outlines how to conduct an eco-investigation of homes, schools, and communities to determine which daily routines waste resources or are harmful to the environment. Examines use of grocery bags, the packaging of products, food and drink, water consumption, the safety of cleaning products, and energy usage in homes. Takes a closer look at paper and other material usage in schools as well transportation in communities. Shows how individuals contribute to the problem and how to be part of the solution of eco-friendliness.
Unless someone like you cares a whole awful lot, nothing is going to get better. It's not, writes Dr. Seuss in this cautionary tale of greed and environmental destruction. Narrated by the villain of the story, the Once-ler, the tale recounts how the Lorax tried to save the Truffula Forest and its inhabitants from disaster at the hands of the insatiable factory owner. The Lorax's pleas are ignored and tragedy follows. A Dr. Seuss classic, it also serves as an ecological warning that still rings true today.
The Magic School Bus is an award winning animated children’s television series based on the book series of the same title by Joanna Cole and Bruce Degen. It is notable for its use of celebrity talent and being both highly entertaining and educational. When Wanda discovers that one of Ms. Frizzle's ancestors was Redbeard the Pirate, she naturally wants to follow the treasure map he left. The map leads the class to a coral reef, where they learn firsthand that life there is risky. To survive, they find, many plants and animals form surprising partnerships.
Goes in search of sustainable solutions. In the Canary Islands, fishermen use rod and line for a valuable species and only take fully mature fish. In Oman, the authorities will only allow fishermen to use one kind of boat and net, and they strictly monitor the catches. Leading decision-makers describe how drastic action must be taken to protect wild stocks and ecosystems, but almost nowhere are measures being taken that help alleviate the crisis. Part one of this series explores the state of global fisheries.
Marine debris comes from many different sources and enters the ocean in many ways. Intentional littering and dumping are big causes. Sometimes the trash goes directly into the ocean, and sometimes marine debris is indirectly generated in a city hundreds of miles from the ocean. When someone litters on the street or parking lot, rainwater can move the trash into storm drains that empty into streams, rivers, and other bodies of water. Improper or careless waste disposal also contributes to this environmental concern. Part of the "Trash Talk" series.
Throughout the world, innovative thinkers and entrepreneurs are transforming their communities, making the dream of sustainable living a reality. The United Kingdom's push for sustainable housing developments raises awareness of energy efficiency and promotes eco-friendly home design. Cement alternatives developed in Australia reduce the carbon footprint for concrete production by 60%. Two industrial designers from Colombia are creating fashion items from recycled tires. In the Philippines, the inventor of coconut fiber nets shows how his company helps prevent devastating mudslides in the region and provides employment to locals.
Elizabeth Hadly has been studying biodiversity in Yellowstone National Park for 30 years. Accompanied by biologist Sean Carroll, she demonstrates different ways in which climate change is impacting the park’s ecosystems. Bark beetles are surviving the winter at higher elevations and killing a large number of white-bark pine trees, disrupting the food web that includes squirrels and grizzly bears. Climate change is also causing ponds to dry up, reducing the pond habitat and decimating the local amphibian population. Although the park provides protected environments for animals, it is not immune from global threats like climate change.
The Grizzly Bear, America's largest, most spectacular predator, was on the brink of extinction in Yellowstone National Park until the 1975 Endangered Species Act made its recovery the biggest success story in conservation history. All wild carnivores need large ecosystems to survive, but when human economic interests, food, or small children encroach into their territory, conflicts between bears and people are inevitable. As we witness the impacts of environmental degradations and human encroachment on the last grizzly habitat in the lower 48 states, we ponder whether this American wilderness icon still faces extinction or if we will be able to co-exist with it.
Access to affordable, sustainable energy supplies is a growing concern around the world. Looks at successful enterprises that are providing some renewable energy solutions. In Scotland, small-scale turbines put wind power within the reach of domestic users. In Sweden, the world's first train to be run solely on biogas has been developed. In Nepal, biogas stoves are improving the quality of life in many ways. And in India, agricultural-plant waste is being turned into solid fuel briquettes for use in industrial stoves and boilers, while a solar-energy company has developed environmentally friendly lighting technology that disadvantaged communities can afford.
During a visit to Thailand, Jeff explores the underwater worlds of the Gulf of Thailand and the Andaman Sea. He also pays a visit to conservationists from Eco Koh Tao who are fighting to restore endangered coral reefs and giant clams. Part of the "Ocean Mysteries" series.
Learn about some of the bold and brilliant ideas researchers and conservationists have to rescue corals and coral reefs from disaster. Part of the "Coral Comeback" series.
Chemist Paul Edmiston’s search for a new way to detect explosives at airports led to the creation Osorb. A swellable, organically-modified silica, or glass, capable of absorbing oil and other contaminants from water. Osorb has become the principal product of a company called ABSMaterials, where Edmiston is now chief scientist. With support from the National Science Foundation, Edmiston and his colleagues at ABSMaterials are developing water remediation technologies for cities and industries. ABSMaterials is creating formulas to address various contaminants, including hydrocarbons, pharmaceuticals, pesticides, herbicides, chlorinated solvents, and endocrine disruptors. Part of the National Science Foundation Series “Science Nation.”
The Magic School Bus is an award winning animated children’s television series based on the book series of the same title by Joanna Cole and Bruce Degen. It is notable for its use of celebrity talent and being both highly entertaining and educational. The debate is intense: Should Walkerville get rid of the swamp by the river and replace it with a fantastic new shopping mall? Carlos, representing his class, is given the task of persuading the town council to keep the smelly old swamp. The kids learn that the swamp is an important habitat and natural water filter, but the council's not convinced until a flood occurs.
The study of thermodynamics can lead to predicting how chemical reactions will proceed or how much energy is required or released during the reactions. To better understand chemical reactions, a new thermodynamic value called “enthalpy” is introduced. Students will examine the practical applications of bond enthalpies, calorimetry, and other measurements of the energy in chemical reactions. They will also see how the understanding of thermodynamics and enthalpy is helping scientists optimize the use of crop waste for biofuels and build more efficient automobile engines. Part of Chemistry: Challenges and Solutions Series.
Kathryn Johnson, an electrical engineer at the Colorado School of Mines, studies large utility-scale wind turbines. Kathryn’s research aims to make the turbines more efficient in order to capture as much of the wind’s energy as possible. Viewers also visit NSF’s National Center for Atmospheric Research, where scientists are working with local utility companies to create an advanced wind energy prediction system. Using data from sensors mounted on each turbine, the system generates a forecast specific to each turbine on a wind farm. This helps the utility company provide as much energy as possible from clean sources.
The rate of a chemical reaction is affected by a number of factors, including temperature and the concentration of reactants at the beginning of the reaction. While the chemical equation may show reactants turning into products as a straightforward process, it is actually involved and precise. How exactly do reactants turn into products? Sometimes, the answer is as simple as two atoms bumping into each other and forming a bond. Most of the time, however, the process is much more complex. Controlling the rate of reactions has implications for a variety of applications, including drug design and corrosion prevention. Part of the series Chemistry: Challenges And Solutions.
Think of earthworms and a few things come to mind: they make great bait for fishing, they aerate the soil, and they’re an excellent addition to a compost pile. But, what a lot of people don’t know is many earthworms are actually invasive species. Earthworms may be small but when they take over a forest, the impact is dramatic. They cause the rapid incorporation of organic material into the soil, changing its structure, chemistry and nutrient dynamics. What's known as the duff layer is suddenly removed, and this duff, or decaying organic material on the forest floor, is habitat for several species of insects, spiders, small vertebrates, bacteria and fungi. It is also the primary rooting zone for most plants.
