The video starts with information about coastal geology and the evolution of birds. It includes amazing footage of white storks, wildebeest, as well as zebras in East Africa's Serengeti region.

California sea lion communication, mating habits, and past and present threats to their survival are discussed. This segment additionally features amazing aerial photography of their rocky coastal habitats.

Marine mammals are the focus of this segment on coastal sea life. Humpback whales mostly swim along the coasts, whether in the Northern or Southern Hemisphere. Seals are semi-aquatic and try to stay as close to the coast as possible, though they'll search for prey in depths of up to forty meters.

We learn about the thousands of kilometers that humpback whales travel from their summer habitat in the polar regions to the tropical or subtropical waters where they spend the winter. Their multi-versed songs and the markings on their flukes are also discussed.

Green sea turtles (the largest hard-shelled sea turtle) and whale sharks (the largest shark and fish overall) are featured in this segment. We also encounter a langouste, otherwise known as a rock lobster, and a moray eel lurking in their coral reef habitat.

This segment looks at the advantages and disadvantages of swarm fish and loner fish, providing insight into their coloration and behavior. Spectacular footage reveals twobar sea bream, trumpet fish, barracudas, and harlequin sweetlips.

Brilliantly colorful parrot fish and two-bar sea bream are among the fish featured in this segment. Sea cucumbers, the vacuum cleaners of all the Earth's oceans, also make an appearance.

Corals are sessile animals, meaning they are immobile and anchored to one spot for the entirety of their lives. Stony coral, leathery coral, and sea fan coral are featured in this segment, along with the beautiful fish that inhabit coral reefs.

Fracking is a controversial topic. This animated video tries to take a neutral look at fracking. It is relevant for all of us, because of high prices for energy and the danger to our drinking water.

The earth's bodies of water are the focus of this film about evolution. As the narrator points out, the vast depths of the earth's oceans remain barely explored.

The narrator explains how the breathtaking rock formations of Antelope Canyon came to be, and why mountains around the world can provide a metaphor for human existence.

The BBC looks at a new and innovative renewable energy invention, Kite Power Solutions. It is estimated that 30 kites could provide electricity for 75,000 homes.

In this segment, the narrator explains where the name Bryce Canyon came from, and why the sand dunes in the US and the large deserts of the world might be related.

We visit Bryce Canyon, where valuable fossils have helped understand the geological history of the planet. The sandstone spires of the canyon are breathtaking.

The Colorado Plateau and the Grand Canyon are just a few of the amazing geographical features of the Southwestern United States.

We learn more about how water interacts with the minerals in the rocks, and visit Monument Valley, a popular spot for filming westerns and commercials.

In this segment, we learn about the role weather plays in the creation of rock formations in the national parks of the United States.

Geysers represent a very popular tourist attraction in Yellowstone Park. How do they work and where do they come from? And what is sandstone? The video answers these questions.

In Yellowstone Park, visitors can see many indigenous animals in their natural habitat and wonder at the park's natural hot springs.

Why are some rock formations and animals found on more than one continent? The explanation dates back to the Ice Age.

Why do some of the national parks in the United States resemble the European Alps? Geologist Dr. Robert Darga answers this question.

While it took Destin eight months to learn how to ride a backwards bike, his young son learned how in two weeks. The son's reward was a trip to Australia, where he got to meet Canadian astronaut Chris Hadfield.

Who knows when we'll discover whether we are alone in the universe or not? Whatever the answer, the quest for more knowledge will never cease, nor grow dull.

Destin Sandlin, an Alabama engineer and YouTube star, shows us how very difficult it is to learn to ride a backwards bike. You think it's going to be a piece of cake, but it's not!
