Our Changing Planet Series 2

Chapter 1: Steve Backshall visits the Maldives, a country facing significant challenges because of climate change. Warming seas and the acidification of the oceans have led to coral bleaching on a massive scale. And increasingly unpredictable weather patterns could deal the final blow. 2022 saw the first mass coral bleaching during La Ni?a, a climate pattern that historically keeps oceans cool enough to avoid bleaching. The earth's reefs are now at a tipping point. But these extreme challenges are galvanising the science community to get out of their labs and into the field, experimenting with more novel and innovative techniques and trialling ideas that could just make a difference. Steve returns to Laamu Atoll to find out about one such cutting-edge project. Professor Steve Simpson and his team from Bristol University have identified that coral larvae, baby corals no bigger than a pinhead, move towards the sound of a healthy reef, a response that guides them to settle amongst a more biodiverse and healthier habitat, and in so doing, add to the coral population. Steve dives with Professor Simpson and records the sound of a healthy reef. With the help of a 360-degree camera, they are able to identify key marine life that make up these coral playlists. Liz Bonnin returns to California to investigate some surprising solutions for the relentless onslaught of the state's wildfire season. California's wildfires are becoming a yearly catastrophe, with the state government spending billions of dollars in the last five years to fight these out-of-control blazes. Liz discovers that ancient forest management techniques and the beaver, a misunderstood mammal, could help prevent them in the first place, providing powerful tools to sustainably protect our planet against the ravages of climate change. Liz visits the traditional reservation of the indigenous Tule River tribe, who have been practising a technique called 'controlled burning' for thousands of years. By regularly burning the twigs and leaf litter that collect on the forest floor, they reduce the amount of material that typically collects in forests and fuels megablazes. Liz joins the tribe on one of their cultural burns and finds out how they have protected their land and, importantly, their sacred sequoia trees. To prevent the fires from moving at speed across the landscape, scientists and indigenous communities are hoping that beavers can help solve the problem. Once found across North America, by 1900 beavers had been hunted virtually to extinction. Liz joins scientist Dr Emily Fairfax, who has been studying the benefits of introducing beavers into a landscape. Surrounded by burnt-out forest, a green oasis sits at it centre, the territory of a beaver family that has created what Emily describes as a 'speed bump' for wildfires. Chris Packham is in Greenland to learn more about the effects of global warming and the rate at which snow and ice are melting and retreating in the Arctic. He travels to a science research station on the island's remote north east coast, one of the most important locations in the world for the understanding of warming in the Arctic and its global impact. Chris joins an Arctic expedition as scientists from Aarhus University and Copenhagen Zoo track across the snow-covered tundra in search of musk oxen, an ice age survivor that can tolerate temperatures ranging from - 40 to +10 degrees Celsius. With the gradual warming of the Arctic, future conditions may not resemble anything the species has ever encountered. Now moving slowly northwards as temperatures rise, there are many questions to be answered: will populations become vulnerable to warm weather disease? How long will they have a territory that's cold enough for them to survive in? And what will they leave behind them? The conditions are gruelling. Chris and the team have to move fast across the vast landscape, hoping to dart and collar 21 of these huge, powerful creatures, taking hair, blood and stomach samples. We learn how the sophisticated collars and an array of science techniques will be able to tell us if they breed, feed, survive or perish in the years to come. Chapter 2: Gordon Buchanan returns to Brazil, Ella Al-Shamahi to Cambodia and Ade Adepitan to Kenya. Gordon Buchanan returns to Brazil, the most biodiverse country on our planet and home to one of the world's most important wetlands, the Pantanal. Gordon's here to revisit a pioneering project that is committed to saving one of the Amazon's iconic predators, the jaguar, and to understand the importance of a healthy ecosystem. The Pantanal is vital to the health of the jaguar's territory. Fed by the Amazon Rainforest's water cycle, it's an extraordinarily rich habitat, and home to an array of water and land species. Gordon takes to the water and sees first-hand how this place is perched on a knife edge. As climate change accelerates, the Pantanal is becoming drier, endangering its wildlife and vegetation, including the jaguar. Gordon hears from a local conservationist how the plans for up-river dams could severely impact this precious ecosystem. Habituating jaguars is a vital part of ecotourism, enabling paying guests to experience these iconic creatures. The profits fund vital research and this year Gordon follows the team on their annual collaring project, darting jaguars and collecting samples and data from these super-sized cats. Once sedated, Gordon gets the opportunity to get hands on with the scientists, witnessing for himself the range of samples and data the team are collecting. This will provide valuable insights into the jaguar's movements within their ever-changing habitat. Ella Al-Shamahi returns to Cambodia, an area experiencing increasing economic growth. This growth is putting massive pressure on natural resources, and is leading to expanding cities and potentially devastating over-exploitation of the natural world. Ella discovers the reality about our planet's most exploited resource after water – sand. The Mekong River is vital to the health of not only this region but to five other countries, and is being dredged for this valuable resource, endangering the structure and health of this mighty river system. Ella takes to the water with a leading Mekong expert to see the extent of the extraction. Unsustainable and highly destructive, mining could possibly sound the death bell for this precious ecosystem. UK scientists are using high quality satellite imagery that reveals the extent of the damage and there's hope that regulation can slow this exploitation. Biodiversity plays a vital role in building resilience in these threatened landscapes. Ella joins an expedition that will reintroduce the nearly extinct Siamese crocodile into the depths of the Cardamom Mountains. To date, the survival of these critically endangered animals has been down to the cultural connection between the local people and the crocodiles, who they consider sacred. Ella and the team are taking ten crocodiles to a safe and very remote site. The crocodiles are inserted into bamboo rolls, which are soaked in water to keep them cool, then bundled onto the back of mopeds and driven to the release site. It's a 24-hour journey, crossing rivers and tackling forest pathways, all the time ensuring the crocodiles are safely stowed. On arrival, the team acclimatise the animals before their final release. We meet those who discovered one of the last remaining crocodiles and an elder of the village explains the role of crocodiles and the natural world to his people. Ade Adepitan returns to Kenya to report on the devastating effect of rising temperatures and failed rains. The conditions are extreme, and the challenges, unimaginable. Both communities and wildlife are fighting to survive the worst drought in 40 years. When Ade visited Kenya in 2021, the elephants were severely affected by drought, but 2022 saw a new and sinister problem. People and elephants were now fighting over dwindling food and water supplies, even killing each other in their desperation to survive. Ade finds out about a project that could help farmers and elephants to co-exist until the next rains finally arrive. Using biology and behavioural science, leading elephant scientists, with the input of locals, have created affordable tools for repelling elephants from farms and reducing conflict. Ade travels to Sagalla, near Tsavo National Park, where its community is leading the way and testing these devices. He meets local farmer Jones, who has created what he calls a 'noisy gun' from tin cans and wood. Other devices include condoms full of chilli powder and beehives strung along fences. Ade finds a community under extreme pressure, but the ingenuity of the 'Human Elephant Coexistence' toolbox is providing a genuine ray of hope.

Life After: Chernoby

The disaster began during a routine systems test at reactor number four of the Chernobyl plant located near the town of Pripyat, on April 26, 1986. After a power surge, an emergency shutdown was attempted and after a subsequent power spike, there was a reactor vessel rupture and a series of steam explosions. The cascading course of events led to exposing the graphite moderator of the reactor to the air, causing it to catch fire. This sent a plume of highly radioactive fallout into the atmosphere. The fallout from Chernobyl prompted mass evacuations as it drifted over an extensive geographical area, including the western Soviet Union and Europe. Over 350,000 people were resettled from contaminated areas of Belarus, Russia, and the Ukraine. Thirty-one deaths are directly attributed to the accident, and all the deaths were among reactor staff and emergency workers. This is the kind of atmosphere Nelson and Ochota are investigating on Life After: Chernobyl as they attempt to determine how the radiation continues to impact the affected areas. They are allowed to stay for as long as they need to in order to conduct their ground-breaking research, but the duo must also be sure to take the necessary safety precautions. Broadway World noted in their Life After: Chernobyl article that by staying in the area for too long, the radiation exposure could reach dangerously high levels in their bodies, and they must always monitor the radiation levels.

In the final episode of the series, Anita Rani investigates the tsunami of single-use plastic that parents pick up in the form of give-away toys. It turns out that McDonald's are the largest toy distributor in the world, handing out over 1.4 billion plastic toys per year worldwide. They claim on their website that they are recyclable, but a visit to Simon Ellin, the CEO of the Recycling Association, makes it very clear that while that may be true in theory, in reality it’s not that simple. Meanwhile, Hugh is in Scotland. He’s learnt that at the same time as the public are trying to reduce the amount of plastics in their lives, the plastics industry has big plans to increase plastic production by 50% before 2040. To find out more, he visits the INEOS factory in Grangemouth, owned by the richest man in Britain, where they produce a staggering 60-70 billion tiny plastic pellets every day.

Suzuki Diaries: Future City

"Eighty percent of us now live in an urban setting, and I think that the solution to our environmental problems is not to say 'we've got break down cities and get everybody back to the land' – that would be disastrous – but we have to make cities our major habitat…we have to make them more in balance, I think, with the rest of the things that keep us alive." David Suzuki Cities are where most Canadians live. And, as we head into the future, how we adapt to the needs of expanding cities will have a huge impact on their livability. Food, land use, housing, energy, waste – how we tackle these issues will determine whether our cities evolve, or whether they decline.

Shattered Ground

As Shattered Ground reveals, some see fracking as a great opportunity for money and jobs, and one that provides cheap, clean fuel. But, for others, the possible human health costs of this new drilling technology have motivated a large and vociferous anti-fracking movement. The debate over fracking has been echoed in the Oscar-nominated documentary Gasland and in Promised Land, the new Gus van Sant's feature film starring Matt Damon. Fracking's critics consider the industry a potential environmental disaster, citing chemical contamination of air and water. With pipelines proposed, terminals for liquefied natural gas (LNG) requiring billions of dollars of investment, and huge shale beds lying underneath highly-populated areas of the Canada and the US (including southern Ontario and the GTA), fracking is an issue that could affect every one of us.

Chris Packham: In Search of the Lost Girl

In 1998, wildlife enthusiast and photographer Chris Packham had a remarkable encounter with the Orang Rimba, a tribe of hunter gatherers in the rainforests of Sumatra, Indonesia. It was the first time he had ever seen people living in perfect harmony with their environment. One photograph in particular that Chris took, a picture of a young tribal girl, has since become immensely important to him as a barometer of how we are treating our planet. In this real-life detective story, with no clues as to her identity or whereabouts other than his original photograph, Chris sets off to Sumatra 20 years on to try to find her; the girl in the picture. Chris's search is further complicated because her tribe is nomadic and often cover vast distances on foot, and since he was last there, millions of hectares of her rainforest habitat has been destroyed. Piecing together the clues, Chris discovers to his horror that the girl's close-knit group of Orang Rimba was attacked not long after he met them, and a number of them killed. But was the girl among them? Chris travels into the heart of Sumatra and tries to discover the girl's fate by meeting the men who pulled the murdered tribespeople's bodies out of the river. On his way, he discovers just how much of Sumatra's once pristine rainforests have been replaced by palm oil plantations, palm oil which is in around 50% of the products we buy in our supermarkets. Chris learns some uncomfortable truths about how we are all in some way connected to deforestation.

Killer Floods

All over the world, scientists are discovering traces of ancient floods on a scale that dwarfs even the most severe flood disasters of recent times. What triggered these cataclysmic floods, and could they strike again? In the Channeled Scablands of Washington State, the level prairie gives way to bizarre, gargantuan rock formations: house-sized boulders seemingly dropped from the sky, a cliff carved by a waterfall twice the height of Niagara, and potholes large enough to swallow cars. Like forensic detectives at a crime scene, geologists study these strange features and reconstruct catastrophic Ice Age floods more powerful than all the world’s top ten rivers combined. NOVA follows their efforts to uncover the geologic fingerprints of other colossal megafloods in Iceland and, improbably, on the seabed of the English Channel. There, another deluge smashed through a land bridge connecting Britain and France hundreds of thousands of years ago and turned Britain into an island for the first time. These great disasters ripped through terrain and transformed continents in a matter of hours—and similar forces reawakened by climate change are posing an active threat to mountain communities throughout the world today.

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.

Colombia with Simon Reeve

Adventurer and journalist Simon Reeve heads to one of the most spectacular countries in the world - Colombia. For 50 years, Colombia has been in the grip of a brutal civil war that has killed more than 200,000 people and displaced seven million. But in late 2016, a peace deal was signed promising to end the conflict and finally bring peace to the country. In this hour-long documentary for the award-winning This World strand, Simon explores Colombia at a pivotal point in its history. He travels into the jungle and comes face to face with the guerrilla army FARC, which is now promising to lay down arms. In the Pacific coast city of Buenaventura, Simon finds out more about the fearsome right-wing paramilitary gangs who now dominate the cocaine trade. As the FARC abandon the countryside, there is a fear that these groups will only grow in power. Travelling in the countryside, Simon meets the coca farmers who are demanding government support to stop growing coca and stop the flow of money to criminal gangs. With land ownership, poverty and drugs at the heart of Colombia's problems, it is in the countryside that the country's precarious future will be decided.

Search for the Super Battery

We live in an age when technological innovation seems to be limitlessly soaring. But for all the satisfying speed with which our gadgets have improved, many of them share a frustrating weakness: the batteries. Though they have improved in last century, batteries remain finicky, bulky, expensive, toxic, and maddeningly short-lived. The quest is on for a “super battery,” and the stakes in this hunt are much higher than the phone in your pocket. With climate change looming, electric cars and renewable energy sources like wind and solar power could hold keys to a greener future...if we can engineer the perfect battery. Join host David Pogue as he explores the hidden world of energy storage, from the power—and danger—of the lithium-ion batteries we use today, to the bold innovations that could one day charge our world.

Power

Drill down to discover the treasures beneath our feet that power our world. Fossil fuels–coal, oil, and natural gas–powered the industrial revolution and allowed us to build a way of life that many cherish today. Personal cars, planes, lights, hot showers–all of these are gifts from our fossil fuels… but they have a dirty dark side in that they are polluting the planet. What is it about these natural resources that have allowed them to fuel our civilization? What secrets are locked in their molecules? Where did that energy come from, and can we find alternative energy resources that come in a cleaner form? The hunt is on for new treasures that might allow us to power our modern way of life without damaging the environment. Join NOVA as we explore the resources that both power and pollute, from modern-day oil prospecting in California, to a mega-city utility company struggling to keep the lights on during hot summer days, to China where an engineer strives to solve one of the greatest obstacles to the success of solar power.

Sonic Sea

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.
