This week we look at why we live where we live in the world's largest island continent. Taking a unique aerial view, viewers discover the peril of sprawl and the struggle for survival on the continental fringe.

Experts agree that bad dog behaviour is mainly down to bad owners and that the owners need to be fixed first. Don't Blame the Dog, is a unique series that challenges young dog owners with bad attitudes to spend a week living with people who depend on dogs - some for their survival in extreme environments around the world, and others who depend on them for their jobs. In an effort to try and better handle their own dogs, these dog owners must first try to master the working dogs.

In the final episode, Richard looks at the Ice Age. 2.8 million years ago the world began to cool. Within a few thousand years much of the planet was shrouded in a dense cloak of ice that would come and go until only 10,000 years ago.

This week we see the mass movement we make across a sprawling land and how our daily habits push systems and networks of transport and data to breaking point. We follow the second busiest air corridor in the world - Sydney to Melbourne - as 150 flights daily prepare for the journey and watch Elyse Fordham as she prepares to captain the first flight of the day. Data visualisation reveals every flight in Australia over a 24-hour period.

In this episode, Richard focuses on the 'KT boundary'. 65 million years ago, a 10 kilometre diameter asteroid collided with the Earth and saw the end of the long reign of the dinosaurs. He investigates the lucky breaks and evolutionary adaptations that allowed some species to survive the disastrous end of the Cretaceous Age when these giants did not.

Three years in the making, this cinema-verite feature from acclaimed filmmaker Joe Berlinger (Brother's Keeper, Paradise Lost, Metallica: Some Kind of Monster) is the epic story of one of the largest and most controversial legal cases on the planet. An inside look at the infamous $27 billion 'Amazon Chernobyl' case, Crude is a real-life high stakes legal drama set against a backdrop of the environmental movement, global politics, celebrity activism, human rights advocacy, the media, multinational corporate power, and rapidly-disappearing indigenous cultures.

In the second part of this four-part epic series, Steve Simpson explores our complicated relationship with the natural world. Attracted by its beauty and fearful of its dangers, Australians are forever locked into a battle with the elements.

Since the emergence of life on our planet more than 3 billion years ago, it has faced a series of devastating catastrophes. Yet somehow, a few special species managed to make it through. How? Professor Richard Fortey travels across the globe to investigate the survivors of history's three biggest mass extinctions and find out what it takes to become a long term survivor.

Our Great Southern Land - Australia - is home to an amazing array of scenery - from the top of the Snowy Mountains to the tropical wilds of the Gulf of Carpentaria, to the irrigated farms of the Murray Darling Basin, the red heart of Uluru and to the ancient forests of Tasmania. In this new ABC series, Professor Steve Simpson takes us on a journey across Australia. From the skies, Steve uncovers the otherwise hidden patterns, rhythms, networks and systems that keep Australia on the move - fed, alive and thriving.

In the final episode, Chris Morgan travels to the far north of Alaska, to the tiny town of Kaktovik. It's early November and winter is coming on. But each year, the polar bears struggle for extended periods on dwindling fat reserves, waiting for the opportunity to hunt on sea ice that takes longer to freeze.

This second episode explores the world of black bears caught in the crossroads of urban development in Anchorage and the wilderness. Some bears are so comfortable living in urban surroundings that their primary habitat is a golf course.

Three of the eight bear species in the world: brown bears, black bears and polar bears can be found in Alaska, one of North America's last truly wild frontiers. In this epic three-part series, ecologist Chris Morgan takes a year-long motorcycle odyssey deep into Alaska's bear country to explore the amazing resiliency and adaptability of these majestic animals.

Every year over 11 million tourists visit the Pacific Ocean, and hundreds perish in its 165 million square kilometres. In this episode, Bear Grylls comes face to face with man-eating sharks in the Pacific, where he must also deal with rip currents, coral reefs and pounding surf. Bear also shows how to survive on a deserted island and live to tell the tale. Includes previously unseen footage and new survival techniques.

By 2010, 40 percent of the worlds coral reefs may be dead. By 2030, half of the Great Barrier Reef may be gone. Parts of it are already dying, but the reasons have not always been clear. Global warming and outbreaks of crown-of-thorns starfish have put extraordinary pressure on the reef. Now scientists have identified another threat sediments, fertilisers and pesticides from agricultural run-off.

With scientists predicting that cities will use three times more energy in 2050 than today, take a look at alternative energy sources, including fusion power.

Marshall Curry's documentary tells a timely story of political action and environmental beliefs at loggerheads. His reconstruction of the recent history and unravelling of the Earth Liberation Front (ELF) is a fascinating exploration of a modern revolutionary movement and its efficacy. Fusing fervent concerns about ecological imbalance and capitalism run amok, ELF members and sleeper cells destroyed facilities involved in deforestation to remove the profit potential from companies wreaking environmental destruction. Broadcast as part of ABC's Sunday Best.

On tonight's final episode of How To Grow a Planet, Professor Iain Stewart examines one of the most underrated but perhaps one of the most important plants in the world - grass. Over eight million years ago, there was a drop in the atmosphere's carbon dioxide levels and as a result, many plants died off. But it was the moment grasses were waiting for, with less carbon dioxide in the air, grass started to really evolve.

Flowers are central to cultures all around the world and are deeply woven into our lives. Since flowers evolved, they have been the driving force of our life. In tonight's second episode of How to Grow a Planet, Professor Iain Stewart discovers how flowers have transformed our planet.
