When a gamma ray burst from two colliding stars hits the atmosphere, the deadly radiation delivers agonizing death and immediately wipes out half the planet. How will the last remaining humans survive?
This episode focuses on the Asia-Pacific side of The Pacific Rim of Fire, which stands as a living testament to the beauty and danger that powerful geologic forces can deliver. The Pacific Rim is home to half of the world's active volcanoes and ninety percent of the world's earthquakes, yet nearly 800 million people continue to live within its violent edge. Our journey begins in New Zealand, a land of volcanoes and earthquakes, where we find a 500-kilometre long slip-strike fault deep under the Pacific Ocean. Geologist Hamish Campbell will take us to the crater of White Island, the country’s most active volcano. Then we'll visit the country's southern island with John Youngson, to find out how New Zealand’s longest fault-line contributes to the gold industry. Finally in Japan, viewers will hike up to Mount Fuji – the iconic peak where science and legend converge, getting up-close and personal with a fault-line witnessing firsthand what it’s like to discover new ways of monitoring, and hopefully one day predicting, seismic activity onboard the world’s most advanced drilling vessels.
Since 1976, the Dead Sea's level has dropped more than 100 feet, leaving its coastline pockmarked with thousands of sinkholes. NOVA follows the unprecedented endeavor to connect the Red Sea to the Dead Sea by way of a massive desalination plant - perhaps the world's largest water chemistry experiment - as scientists race to save the Dead Sea and bring water to one of the driest regions on Earth.
Modern life would be impossible without plastic – but we have long since lost control over our invention. Why has plastic turned into a problem and what do we know about its dangers? This video is a collaboration with UN Environment and their Clean Seas campaign, If you want to take action to turn the tide on plastics, go to http://www.cleanseas.org and make your pledge.
Sonic Sea is a documentary about the devastating impact of industrial and military ocean noise on whales and other marine life. The film begins with a mystery: the unexplained stranding and mass mortality of several species of whales in the Bahamas in March 2000. As the mystery unfolds, the film explores the critical role of sound in the sea, and the sudden, dramatic changes human activity is inflicting on the ocean's delicate acoustic habitat -- changes that threaten the ability of whales and other marine animals to prosper, to function, and ultimately, to survive. Sonic Sea features several charismatic scientists, including Ken Balcomb, the former Navy pilot and acoustics expert who proved to the world that naval sonar is killing whales, as well as the musician and environmental activist, Sting, whose moving interview connects the sonic world of marine life with our sonic world on land. The film offers solutions (and, by extension, hope) for a quieter ocean, and underscores that the ocean's destiny is inextricably bound with our own.

A crew of women embarked on an ambitious sailing expedition around the UK to raise awareness of ocean plastic and sample the water to see what damage is being done. Hannah Thomas-Peter joined them on the month-long voyage and documented their voyage of discovery.
