As summer spreads across our planet, honey bees toil, snow geese breed, tadpoles awaken and lions stalk wildebeest in search of lush grass.
Our planet is solar-powered. But due to the Earth's tilt, it doesn't strike its surface evenly. This solar energy arrives in varying amounts at different times of the year. The huge increase that comes with summer also triggers countless migrations.

New discoveries have rewritten the history of our solar system, revealing a complex and violent story that begins with the birth of our Sun from the debris of a massive galactic collision, to its eventual fate as a lone zombie star.
It is a dramatic history of elegant beauty and extreme violence. The inner solar system was like a congested highway. Planets crossing lanes, frequent collisions. There were a lot of planets that could have made it but didn't, and we just happen to be one of the lucky ones that did. The players in our solar system's story are more tangled up than we ever imagined. Without all of these things interplaying, the Earth wouldn't have the stable environment that we have today, and life wouldn't be able to exist.

Earth's history is marked by one cosmic disaster after another, forging the path of human evolution. Asteroid and comet collisions, flares from the Sun, mass extinctions, supernova explosions, cosmic ray bombardment. You name it, we've experienced it. It's kind of a miracle we're here at all. Now, experts explore how the Earth has teetered on the verge of destruction.

One man has seen more of the natural world than any other. This unique feature documentary is his witness statement. In his 93 years, David Attenborough has visited every continent on the globe, exploring the wild places of our planet and documenting the living world in all its variety and wonder. Now, for the first time he reflects upon both the defining moments of his lifetime as a naturalist and the devastating changes he has seen. Honest, revealing and urgent, this film is a powerful first-hand account of humanity's impact on nature and a message of hope for future generations.

This revealing film examines how human activity is setting off dangerous warming loops that are pushing the climate to a point of no return - and what we need to do to stop them. With captivating illustrations, stunning footage and interviews with leading climate scientists as well as support from Greta Thunberg and the Dalai Lama, 'Earth Emergency' adds the missing piece of the climate puzzle.
Narrated by Richard Gere, the film examines four of the major warming feedback loops threatening our planet: Forests, Permafrost, Albedo and Atmosphere.

Will Smith confronts his fear of nature on powerful white-water rapids in Iceland. "Over five expeditions, I've followed explorers into situations that were straight-up scary. It was worth it to discover the Earth's wonders. But your boy was tripping more than once. Because when I see wilderness, you know, nothing but nature, I get nervous because I don't understand it."
