The Deepest Place on Earth

The discovery of the Marianas trench was one of the first puzzle pieces that lead to the understanding of the most massive process that shapes the geology of the Earth; plate tectonics and the creation of new crust in the mid-ocean ridges and its subduction under the continents.

Loch Ness

Scotland is a ground zero for some of the most significant geologic cataclysms in Earth's history. Understanding of these titanic shifts was prompted by a mysterious lake known as Loch Ness.

Driest Place on Earth

Chile's Atacama Desert is the driest, oldest and deadest desert on earth. Yet it's plays host to living creatures and penguins even thrive nearby. It may provide clues to where to look for life on other, seemingly barren, planets.

Great Lakes

The Great Lakes region provided geologists with much of the evidence for the frequent ice ages that visited North America. But the lakes may be a rather transient feature of the continent dependent upon the recurring ice ages to maintain their existence.

Tsunami

A tsunami is a dramatic indicator of geological activity magnifying the impact into extensive coastal destruction. Scientists searching for evidence of past tsunamis to predict when they are likely to recur and how severe they are likely to be uncover a new phenomenon, the mega-tsunami.

Asteroids

Most major geological processes require millions of year to become noticeable. Meteor impacts are exceptions which can cause comparable changes in seconds.

Hawaii

The Hawaiian Islands are a study in contradictions. The fastest growing islands on earth are also the fastest disappearing. Made of one of the hardest minerals, it crumbles at a touch. The world's most active volcano is nowhere near the typical volcanic regions. Geologists strive to understand these mysteries.

Alps

The Alps are known as the majestic mountain range of Europe. But their formation from a collision between Europe and Africa left an unstable structure that is now a classic study in erosion by rivers of water, ice and rock suggesting an even greater former glory. Left unexplained is why the Mediterranean Sea exists between the continents.

Our Changing Planet

The launch of the BBC's ambitious seven-year natural history project, in which six presenters visit six of the planet's most threatened ecosystems to meet the people fighting to restore the Earth's delicate balance. Chapter 1: Steve Backshall travels to the Maldives, an area facing significant challenges because of climate change. Warming seas and the acidification of the oceans have led to coral bleaching on a massive scale, destroying the surrounding ecosystem. The biodiversity of the reefs provides food security, income and other benefits to the people of the Maldives, and Steve finds that they are working hard to try to stem the tide of destruction. He also goes diving off the reefs to check on a group of manta rays, whose presence offers a clear indication of the health of the reef. In Iceland, Chris Packham learns more about the effects of global warming. Temperatures in the Arctic are rising at more than twice the annual global average. Snow and ice are melting at an increasing rate, which contributes to rising sea levels and is likely to provoke extreme temperature events beyond the Arctic. As one of the eight Arctic States, Iceland is being dramatically affected by rising temperatures, with the lives and livelihoods of many islanders being threatened. Chris also discovers that melting sea ice is opening the Arctic to navigation. These seas are home to many species of whales, so Chris joins a team of young scientists monitoring the impact of increased commercial shipping on humpback whales. On the other side of the world, Ella Al-Shamahi visits Cambodia in Southeast Asia, an area experiencing increasing economic growth. However, growth is putting massive pressure on natural resources, with ever-expanding cities and devastating overexploitation of the natural world. The Mekong river is the lifeblood of this region, but whole sections of it are under pressure. Ella meets a fishing community living on the Tonle Sap lake. The lake used to offer rich fishing grounds for local communities, but the construction of many dams along the wider Mekong is now threatening to destroy the biodiversity of this once abundant lake. The building of new roads has given poachers easier access to forests, and the illegal wildlife trade is big international business. Ella visits a project in Cambodia that rescues and rehabilitates illegally trafficked wildlife, including pangolins, the most trafficked mammal on Earth. Chapter 2: Liz Bonnin travels to California to learn about the increasingly invasive wildfires hitting the headlines. Scientists can see clear links between the fires, climate change, raised temperatures and an extended drought season. There is one crucial element that is key to a sustainable future in California: biodiversity. Loss of keystone species and large carnivores is a threat to the state's ecosystems, and conservationists and scientists are mobilising to save wildlife from wildfires and to treat their burns. Liz also visits the Pacific coast of California, where warming seas have brought with them a new resident, great white sharks. With each shark consuming up to 18 kilos of prey at a time, the impact they could have on the marine ecosystem is being studied intently. Ade Adepitan travels to Kenya to look at the effects rising temperatures are having on the land. Hundreds of millions of Africans depend on rainfall to grow their food and keep livestock, and the capacity for adaptation is low. Ade also visits a project in Kenya that is going to extraordinary lengths to safeguard the future of its most charismatic creature, the African elephant. Over in Brazil, Gordon Buchanan discovers a pioneering project that is trying to save one of the Amazon's iconic predators, the jaguar. Brazil is the most biodiverse country in the world, and as well as the Amazon rainforest, it is home to one of the world's most important wetlands, the Pantanal. This area is home to high numbers of jaguars, but in 2020, wildfires destroyed 30 per cent of the Pantanal, killing an estimated 17 million animals. More than a quarter of the resident jaguars were directly impacted by these fires, through habitat loss, food shortages, injury and death.

How to Change the World

This feature documentary tells the story of the story of the pioneers who founded Greenpeace and defined the modern green movement. In 1971 a brave group of young activists set sail from Vancouver in an old fishing boat. Their mission: to stop Nixon's atomic bomb tests in Amchitka, a tiny island off the west coast of Alaska. It was from these humble but courageous beginnings that the global organisation that we now know as Greenpeace was born. Chronicling the fascinating untold story behind the modern environmental movement and with access to dramatic footage that has not been seen for over 40 years, this gripping new film tells the story of eco-hero Robert Hunter and how he, alongside a group of like-minded and idealistic young friends in the '70s, would be instrumental in altering the way we now look at the world and our place within it. These campaigning pioneers captured their daring and sometimes jaw-dropping actions on a range of film cameras and Greenpeace granted acclaimed director Jerry Rothwell access to this vivid archive to make his thrilling, sometimes terrifying film. Greenpeace was born in 1971 when a ragtag group of journalists, hippies, and scientists living in Vancouver tried to stop a US atomic test. Fortunately, they were media savvy from the beginning, capturing their seat-of-their pants activist adventures on film. The youthful energy is palpable in action-packed scenes, including one in which activists confront a Russian whaling ship in a tiny Zodiac dingy. Soon, though, idealism comes up against reality, compromise, human nature, and the complexities of managing a growing organization. This insightful film is also a vibrant, moving reflection about the ongoing struggle to balance the political and the personal.
