It's death on an unimaginable scale, when a majority of Earth's species quickly die out. It's called "mass extinction," and it's happened at least five times before. Cataclysms, such as supervolcanoes or asteroids, are thought to cause these events, but some experts believe a man-made mass extinction could be next. Is our planet in trouble? And if so, is there anything we can do to stop the next catastrophic annihilation? Experts are traveling the world, performing groundbreaking scientific detective work to answer these very questions.
In the wilds of the Canadian Rocky Mountains, a mother moose tends to her newborn calf. Spring is in full swing, but this far north, winter is never far away and, with hungry bears and wolves for neighbours, many challenges lie ahead. Local cameraman Hugo Kitching knows this only too well, but he is determined to follow the mother and calf through the four seasons. What unfolds is a very intimate story, and when Hugo finds a second moose calf born late in the year, things take an unexpected and dramatic turn.
The Taiga forest, on the edge of the Arctic, is a silent world of stunted conifers. The trees may be small but filming from the air reveals its true scale. A third of all trees on Earth grow here and during the short summer they produce enough oxygen to change the atmosphere.
The world's cities are growing at a faster rate than any other habitat on the planet. And while most of us imagine them to be concrete jungles devoid of nature, for animals of all shapes and sizes they are just a new habitat filled with new and surprising opportunity. With similar needs to humans, these wild animals face similar challenges, and like us, if they play their cards right, they can find everything they need in the city. With the natural world shrinking, and our urban centres continuing to grow, adapting to life in the city has never been more important. This first episode examines what it takes for these wild residents to thrive in the newest and fastest changing habitat on the planet. From smooth-coated otters at home in Singapore and huge colonies of megabats in Adelaide to reticulated pythons living on the streets of Bangkok, experience our cities through fresh eyes - the eyes of the animals that live in them, and discover a wilder side to a world we think we know.
