The Taiga forest, on the edge of the Arctic, is a silent world of stunted conifers. The trees may be small but filming from the air reveals its true scale. A third of all trees on Earth grow here and during the short summer they produce enough oxygen to change the atmosphere. In California General Sherman, a giant sequoia, is the largest living thing on the planet, ten times the size of a blue whale. The oldest organisms alive are bristlecone pines. At more than 4,000 years old they pre-date the pyramids. But the baobab forests of Madagascar are perhaps the strangest of all.

Will explore the strategy, deception and feats of engineering plants use to thrive in the changing weather of different seasons. In the face of conditions ranging from ice and snow to raging fires, survival is often a question of perfect timing - particularly when contending with intense competition and surprising predators.
In this episode, David Attenborough travels to Finland to show one of the most extreme examples of seasonal plant life in the Arctic Circle. He also travels to California to see how climate change is affecting giant sequoias. These ancient trees like all other seasonal plants depend on the predictability of the seasons and our current changing climate threatens their survival.

Filmmaker Ali Tabrizi initially set out to celebrate his beloved ocean, but instead found himself examining the harm that humans inflict upon the vulnerable seas. From plastics and fishing gear polluting the waters, to the irreparable damage of bottom trawling and by-catch, to illegal fishing and devastating hunting practices, humanity is wreaking havoc on marine life and, by extension, the entire planet. What Tabrizi ultimately uncovered not only challenges notions of sustainable fishing but will shock anyone who cares about the wonders of ocean life, as well as the future of the planet and our place on it.
From the co-creator who brought you the groundbreaking documentary Cowspiracy comes Seaspiracy, a follow up that illuminates alarming -- and not widely known -- truths about the widespread environmental destruction to our oceans caused by human behavior.

Dave Grohl returns to his musical roots, while the Foo Fighters prepare to record at Seattle's Robert Lang Studio with Death Cab for Cutie's Benjamin Gibbard. Dave sets his focus on the Seattle music scene, mainly the grunge movement and its implications in American Rock Music. Interviews with Chris Cornell, Nancy Wilson, Bruce Pavitt.

Within the earth, right beneath our feet, are strange and sometimes deadly secrets. Earthquakes, tsunamis, and volcanic eruptions are just some of the phenomena that are driven by hidden forces deep inside our planet. With the latest sensors and surface scans, a virtual X-Ray of the earth can be generated for study.
In the first episode, we will explore how a vast fault 80 miles off the Pacific Northwest coast. With pressure building for over 300 years, a slip would result in a megaquake and tsunami that will devastate the region threatening 15 million people.

20 years ago, two astronomers made a remarkable discovery, one which would change the way we view the universe for ever. A planet outside our solar system, orbiting a distant star - an exoplanet. Since then, we have found worlds where it rains diamonds, ones that boil at 3,000 degrees centigrade and even a world with four suns in its sky. But the big question is - will we ever find another Earth? As we close in on the discovery of the 2,000th planet outside our solar system, or exoplanet, we investigates the techniques that are revealing so much about these alien worlds. The documentary asks if we are really any closer to finding another world like our own - a second Earth.
