The climate is changing faster than ever, which is why 'fix our climate' is one of the five goals of the Earthshot Prize. Prince William, Sir David Attenborough and Christiana Figueres highlight inspiring and often unexpected solutions to the challenge. In this film, we'll explain the scale of the problem posed by climate change and will introduce you to some amazing people already working on climate crisis. One of these three finalists will win the Earthshot Prize and get the platform and resources they need to scale their ground-breaking work. Nine more solutions for fixing our climate will receive the same support over the course of this decade.

'Just Do It: A Tale of Modern-day Outlaws' lifts the lid on climate activism and the daring troublemakers who have crossed the line to become modern-day outlaws. Documented over a year, Emily James' film follows these activists as they blockade factories, attack coal power stations and glue themselves to the trading floors of international banks despite the very real threat of arrest.

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.

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.

In the spectacular deserts of coastal Peru, archaeologist Dr Jago Cooper explores the dramatic rise and fall of Chimor, the first empire of South America. His journey begins among the ruins of a vast lost city once home to an all-powerful monarchy, whose subjects transformed the desert landscape, created gold and silver treasures and believed so strongly in the power of their gods that they made the most shocking of sacrifices. Chimor thrived despite facing some of the most extreme climate conditions in the world, but not even this powerful empire could withstand the forces that eventually destroyed it.

Everything that lives on land, animal or plant, depends on fresh water. Yet only part of it is within reach: Much of the planet's fresh water, is locked away, almost two-thirds of it lies frozen around the poles. Even away from the poles, much of the land's fresh water freezes each winter. The need for fresh water is as strong as ever. However, the supply is becoming increasingly unpredictable and uncertain for all manner of species. We are not alone in our need for water, but we have the ability to ensure the fresh waters of the world do flow, and we alone can determine how they are shared.
