Around the globe, unique species face extinction from hunting and habitat destruction. George, a Pinta Island tortoise from the Galapagos Islands, is the very last of his kind. Other species were on their way to joining George as the last of their kind--until help arrived.
In this episode, host Emily Graslie explores de-extinction. However, for this to happen scientists must find viable DNA. They must also account for environmental effects on a developing fetus. Part of "The Brain Scoop" series.
Is a sixth mass extinction on the horizon? Dr. Anthony Barnosky and Kaitlin Maguire travel to the John Day Fossil Beds National Monument to find, collect, and date fossils. They have determined that the rate at which animals are going extinct today is much faster than normal.
Six researchers share 60-second stories about organisms that may be gone, but not forgotten. Researchers and scientists study these stories to get a better understanding of the complexities of life on Earth. Part of the "Shelf Life" series.
The United States Geological Survey (USGS) conducts research on the desert tortoise in the Mojave Desert with the hopes of allowing the species to recover and escape the threat of extinction.
What does it mean to be an endangered species? Are endangered species destined for extinction? Host Emily Graslie explores some of these questions in celebration of Endangered Species Day. Part of "The Brain Scoop" series.
Travels to over a dozen locations exploring the state of global fisheries. Explores the consequences in the Indian Ocean of nets with mesh so fine that even seawater only trickles out, the potential extinction of tuna in the Mediterranean and the North Atlantic, and the impact of land-based sources of pollution on coastal fishing areas. Part two of this series reports on the search for solutions.
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.
Synapsids were the world’s first-ever terrestrial megafauna, but the vast majority of these giants were doomed to extinction. However, some lived on, keeping a low profile among the dinosaurs. Part of the “Eons” series.
Over a thousand dinosaur species once roamed the Earth. Learn which ones were the largest and the smallest, what dinosaurs ate and how they behaved, as well as surprising facts about their extinction.
This series explores the relationship between humans and the sea and focuses on the life of the sea turtle. Turtles worldwide face serious threats of extinction; however, conservation efforts are trying to preserve this species. Part of the "Turtle World" series.
In Cambodia's Mekong River, the giant catfish is in danger of extinction. Can it be saved? Segment of video from Wild Chronicles Series.
Students explore the important role the environment plays in everyday life. Several environmental problems are highlighted, with a focus on pollution and global warming. Additional concepts and terminology discussed include ecology, biological extinction, resource depletion, overconsumption of resources, fossil fuels, global climate change, and natural resources.
The dinosaurs were headed for trouble. They ate nothing but junk food. They never brushed their teeth. They stayed up all night, and they jumped off cliffs even though they could not fly. To avoid extinction, they evolved into birds.
In this episode, host Emily Graslie sets the record straight on prehistoric life and misconceptions found in sci-fi movies. Part of "The Brain Scoop" series.
