Planet Earth has been home to humankind for over 200,000 years, but with a population of 7.3 billion and counting and limited resources, this planet might not support us forever. Professor Stephen Hawking thinks the human species will have to populate a new planet within 100 years if it is to survive. With climate change, pollution, deforestation, pandemics and population growth, our own planet is becoming increasingly precarious. In this landmark film Professor Hawking, alongside engineer and radio astronomy expert Professor Danielle George and a former student, Christophe Galfard, join forces to find out if, and how, humans can reach for the stars and relocate to different planets. Travelling the globe, they meet top scientists, technologists and engineers who are working to answer our biggest questions: is there another planet out there that we could call home? How will we travel across the vast distances of space to get there? How will we survive the journey? And how will we set up a new human civilization on an alien world? Travelling the globe, they meet top scientists, technologists and engineers who are working to answer our biggest questions: is there another planet out there that we could call home? How will we travel across the vast distances of space to get there? How will we survive the journey? And how will we set up a new human civilization on an alien world? Taking in the latest advances in astronomy, biology and rocket technology from the Atacama Desert to the wilds of the Arctic, viewers will discover a whole world of cutting edge research. This programme shows that Professor Hawking’s ambition isn’t as fantastical as it sounds - and that science fiction is closer to science fact than we ever thought.

Nearly a generation after the acclaimed Blue Planet documentary was released, David Attenborough returns to narrate this groundbreaking sequel/reboot. Blue Planet II focuses more heavily on mankind's influence on the world's oceans through both global pollution and climate change. This series features a variety of revolutionary segments never before seen in a video documentary. One Ocean Footage of marine life in different environments around the north, beginning with a tropical coral reef which has medicinal properties for dolphins, and is used as a tool by tusk fish. In Japan, a shipwreck is home to the Asian sheepshead wrasse, which can change gender, while in the polar north, walruses struggle to find ice floes for their pups to rest on as climate change takes its toll on the environment.

Hosted by ABC journalist Bob Woodruff, this two-hour special explores what a worst-case future might look like if humans do not take action on current or impending problems that could threaten civilization. The problems addressed in the program include climate change, overpopulation, and misuse of energy resources. The events parallel the life of a fictitious storyteller, 'Lucy' as she describes how the events affect her life. The program included predictions of a dystopian Earth in the years 2030, 2050, 2085, and 2100 by scientists, historians, social anthropologists, and economists, including Jared Diamond, Thomas Homer-Dixon, Peter Gleick, James Howard Kunstler, Heidi Cullen, and Joseph Tainter. According to Executive Producer Michael Bicks, "this program was developed to show the worst-case scenario for human civilization. Again, we are not saying that these events will happen — rather, that if we fail to seriously address the complex problems of climate change, resource depletion and overpopulation, they are much more likely to happen.

The search for climate change solutions requires passion, resources and a sense of urgency -- three qualities Bill Gates clearly possesses. Bill has founded a start-up called TerraPower. After extensive computer modelling, the idea showed promise. Its new reactor greatly reduced the chance of human error. Fuelled by depleted uranium, the travelling wave reactor functions like a slow-burning candle and requires refuelling only once every decade. Bill and his team believed they had finally developed the ideal energy source, a reactor that was clean, efficient, and most importantly, safe.

Explore how Artificial Intelligence will change your job as new research shows how much of what you do could be done by robots. From truckers to lawyers & doctors, we bring affected workers face to face with AI experts. How can we prepare for the coming changes to the world economy? We are on the precipice of another technological transformation. The last industrial revolution turned society upside down. It ultimately delivered greater prosperity and many more jobs, as well as the eight hour day and weekends. But the transition was at times shocking and violent.
The question is, can we do better this time? We don't realize that the future is not inevitable. The future is the result of the decisions we make today. These technologies are morally neutral, they can be used for good or for bad. There's immense good things they can do, they can eliminate many disease, they can help eliminate poverty, they can tackle climate change. Equally, the technology can be used for lots of bad. It can be used to increase inequality,it can be used to transform warfare. It can be used to make our lives much worse. We get to make those choices.

Journeying from pole to pole, The series 'Frozen Planet II' reveals surprising worlds that exist across the planet and the remarkable animals that make them their home. In a fragile world of beauty and hostility, nature finds a way to survive and thrive. David Attenborough explores a planet on the brink of major change.
In the first episode, we begin our journey in the far south, in the most hostile place on earth, the frozen continent of Antarctica. After being raised on the ice in winter, emperor penguin chicks find themselves abandoned by their parents in spring. To survive, they must find their own way across the treacherous sea ice to the rich waters of the Southern Ocean.
The waters surrounding Antarctica may be the richest of all, but they are also home to an exceptionally sophisticated predator, the killer whale. To reach their favored prey, Weddell seals, a family of killer whales have learnt to generate their own waves, washing the seals off their ice floes. It’s a technique that has been passed down over generations and is coordinated by the family matriarch, who can be over 100 years old.
Leaving Antarctica and travelling north, we discover frozen habitats that are created by altitude. The greatest of these is the Himalaya, the tallest mountain range on earth, which contains so much ice and snow it is known as the third pole. In the shadow of the Himalaya lies a vast frozen grassy plain that is home to the fluffiest cat in the world, Pallas’s cat. It may have extremely dense fur, but if it’s to survive the Mongolian winter, it needs to catch lots of gerbils and voles. Easier said than done when you only have short legs and paws that are sensitive to the cold.
North of the Great Steppe lies the boreal forest, which encircles the continents of North America, Europe and Asia, and remains frozen for six months of the year. Prowling these forests in the far east of Russia is the Siberian tiger, the largest cat in the world. In winter, it is on the lookout for black bears hibernating in caves, a high-risk strategy that only a cat of this size would attempt.
Above the boreal forest, we cross into the Arctic Circle, where conditions become so extreme that trees can no longer grow. This is the tundra. Living here are relics of the last ice age, musk ox. In spring, their calves face a far greater danger than the cold, grizzly bears. Encounters can be brutal, but if just a few calves survive the gauntlet, the herd’s future is secure.
To the north of the tundra is the Arctic Ocean, the only ocean that can completely freeze over. Living here is one of the most peculiar animals on earth, the hooded seal. Males have extraordinary inflatable noses, producing a bright red balloon out of their left nostrils. One male hopes this will make him irresistible.
All of the frozen habitats share one thing in common: the threat posed by today’s climate change. Travelling to the island of Greenland, home to the largest body of ice in the northern hemisphere, we witness how global warming is melting its ice cap at faster rates than ever before, with profound consequences for global sea levels. Lastly, we visit the Arctic’s most iconic resident, the polar bear, as a mother bear struggles to provide for her cubs in a world of shrinking sea ice.
