35 years after the Chernobyl disaster, Ben Fogle travels to the most radioactive place on Earth. He spends a week living alone inside the Chernobyl Exclusion Zone, gaining privileged access to the doomed Control Room 4 where the disaster first began to unfold.
'The planet faces unprecedented challenges - many of them, like Chernobyl, of our own making. What I've discovered in Chernobyl is that nature's reclaiming it. This is the greatest, accidental rewilding project of the globe. For me, the really exciting part of the Chernobyl story is the accidental hope that came from it. '

Our planet is one in a billion. How incredible, awe-inspiring life is driven by its natural forces - and how we can ensure humans become a force for good. David Attenborough narrates a series revealing how the forces of nature drive, shape and support the Earth's great diversity of life.
The first edition examines volcanoes, which responsible for both for the planet's breathable atmosphere and the oceans, but are also the architects of the planet, with over 80% of the Earth's surface being the result of magma bursting up from the molten interior - providing a platform for life.

From the frozen poles to the searing deserts, this episode shows how animals have come up with strategies to survive the uneven amounts of sunlight that fall on our planet over the course of a year. The exception is on the equator, where the duration of day and night remain the same throughout the year. Here, this guaranteed sunlight drives the great diversity of life in the tropical jungles.

As tides rise and fall twice a day, vast amounts of water swirl around the earth. This is a huge energy source that's currently largely untapped. An estimated 3000 gigawatts are available to be harvested globally, enough to power a third of the earth's homes. Yet compared to wind and solar, the technology needed to harness tidal power is still in its infancy. The power of the ocean’s tides is the last great untapped energy source on Earth. From sub-sea kites to floating platforms, teams of engineers are racing to perfect the technology to harness the vast flows of water.

Weather controls the distribution of freshwater on Earth. David Attenborough narrates how this uneven distribution has given rise to an incredible diversity of species and habits, from the driest desert to the lushest tropical rainforest. Featuring a colony of ants banding together into a raft every time its home in the Amazon floods, a rain frog that manages to eke out an existence in one of the world's driest habitats on Earth, and the last wild camels that survive the Gobi Desert's bitter winters by eating snow that blows in from Siberia.

The world's shipping industry is facing a major challenge. If global shipping were a country it would be the sixth largest producer of greenhouse gas emissions. At current growth rates, if we do nothing, those emissions could double or even triple by 2050. But shipping companies and engineers are creating remarkable new machines to make their industry greener, using a resource that has moved man across the world’s oceans for thousands of years…Wind.
