Explores the open savannahs of Africa, particularly the mammals that inhabit them and the trees that border the grasslands. Shows how the different animals interact with each other and the non-living elements of their habitat to maintain a healthy balance. Also investigates the threat from an increasing human population for homes, food, other resources, and the resultant threat to the survival of many animal groups. Looks at international breeding programs around the world, which were established to protect these animals and enable them to reproduce in captivity, so their gene pool is preserved.
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.
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.

What do you know about bats? Are they our friends or enemies? Emphasizes that bats help us with pollination, seed dispersal, and by eating millions of bugs. Discusses their habitats and the foods they eat. Shows that their appearance and size differ. Closes with a warning that bats are wild animals.
The parakeet starts without a script because Boronitas, the screenwriter, is sick. Amanda decides to improvise and presents the guest: the rabbit, who failed the school year because the llama failed to turn in an assignment. When the llama arrives with the script, they tell her it's already late and complain about her lack of responsibility. She explains that she took too many jobs at a time and failed to comply. Then Eva and Maite say they don't understand why humans say yes to everything, even bad things like smoking, drinking, and others. the celebrity guest, Maradona former soccer player, who said no to food. At the end the parakeet explains the importance of learning to say no.
An energy source unrivaled in efficiency and power, oil is the driving force behind today's industries and economies. It touches nearly every aspect of our daily lives, from our food and our clothing to our cars, yet most of us know very little about it. Traces the story of oil through the centuries, from its birth deep in the dinosaur-inhabited past to its ascendancy as an indispensable ingredient of modern life. Yet many experts predict that we have already passed peak production of this vital natural resource, with the latest scientific evidence suggesting that our headlong rush to exploit the remaining reserves may have profound--and perilous--impacts on our future.
One of the fifteen parts of the "Farm to Market" series. A vegetable can be the stem, leaf, root, or even the flower of a plant. Documents the growth, maturation, and harvest of several kinds of vegetables, highlighting their similarities and differences. Follows along as these foods are packaged for market.
Part of "Show Me Science" series. Are animals intelligent? Bees communicate with each other. Monkeys use rocks and sticks to help them get food. Is this instinctual or is it evidence of thought? Some scientists believe that one measure of intelligence is self-awareness, and that an animal's reaction to its own image in a mirror can tell us whether or not it is self-aware. Looks at fish, birds, monkeys, and primates and their reactions to themselves in a mirror. Researchers look for signs of self-recognition as they observe, record, and interpret the reactions of these animals. Includes suggestions for careers in this field of study.
Moko is an explorer. As he travels the world continent by continent, he makes many friends and discovers many natural phenomena which sometimes delight him, and other times scare him. Each animated episode recounts an adventure and takes an "original story" approach to explaining these natural phenomena. In this episode, Moko is enjoying Alarick's country. The warm weather has returned, the trees have flowered and food is plentiful. Moko thinks now the cold has passed life here will be easy. An old man tells him that the cold will return, but Moko doesn't want to believe him and lets time pass. He sees the beauty of the changing seasons and one morning...winter!

The image of a rat sniffing around for food with its little whiskers moving back and forth to help satisfy its appetite is enough to make most people lose theirs. But those whiskers play a valuable role in helping rats determine what is in the environment around them. With support from the National Science Foundation, Mitra Hartmann and colleagues at Northwestern University in Chicago are constructing whiskered robots that can detect and then project three-dimensional virtual images of objects on to a computer screen. Scientists here don't think it's so far-fetched that one day robotic rovers, much like the ones on Mars now, might contain a set of whiskers to help them navigate the terrain around them.
Climb aboard the Cyclops, a microscopic research vessel, and investigate an amazing hidden world on which all living things depend. The Cyclops houses a team of scientists known as the Micronauts and guides them through their discoveries of biological classification, diversity, and ecology. While navigating the dense aquatic weed forest of the pond, the Cyclops is pulled off course by a hydra. After escaping its tentacles, the crew begins to study how the hydra reproduces, captures its food, and digests its prey. One of the Micronauts takes a journey inside the hydra’s digestive system to get a first-hand account of the digestive process. Part 4 of the Microscopic Monsters Series.
