The Earth

A variety of cosmic events have both helpful and harmful effects on life on Earth. From the beauty of the Aurora Borealis and rainbows to the dangers of UV radiation and cosmic rays, from the miracle of photosynthesis to the thrill of a meteor shower, this episode explores how the effects generated by the sun and other extra-solar sources can literally get under our skin, scramble our technology, make life possible and threaten our existence all at the same time

It has taken 4.6 billion years for the Earth to evolve from a barren rock into the world we know today. Explore the forces beyond our planet that have determined Earth’s destiny -- forces of destruction and regeneration in the solar system that created the planet and still protect it. And now the remarkable planet is facing a new challenge: humankind. The question is, how will it survive?

Did you know that 1% of the white noise you see on old televisions is background radiation from The Big Bang? That the gold on a wedding ring comes from a star that exploded 5 billion years ago? And, that we're connected to the salt water of the first oceans through the water in our bodies? Our human story is actually 14 billion years old and the clues are all around us. This CGI-driven special will tell the history of our world in two hours, an ambitious story that will give surprising connections to our daily lives. From the formation of the earth and the emergence of life, to the advance of man and the growth of civilization, it’s a rapid-fire view of our unforgettable story.

The extraordinary story of Earth and why it is special and uniquely brimming with life among a largely unknown but harsh cosmic arena. It will be told by eight astronauts from their unique perspective of being away from Earth. In the first episode, Astronaut Chris Hadfield reveals the unlikely and unexpectedly interconnected systems that allow life on our planet to breathe.

At a time when the Earth’s surface is changing faster than ever in human history, watch cities grow, forest disappear and glaciers melt.
In the ever-growing grey of cities one man is feeding thousands of parakeets; in Sumatra a female orang-utan and her daughter face life in a forest under threat; while in Tanzania local people use satellites to replant a forest, securing the future for a family of chimpanzees. This is our home as we’ve never seen it before.

Volcanoes are one of nature’s most awesome and destructive forces, but they are also the life force and architect of our planet. They can raise up great mountains and create new land, or they can level cities and destroy entire civilizations. They provide a glimpse of the power of Earth’s internal heat source, without which it would have become a dead planet millions of years ago. In this episode, Iain takes us on a journey to some of the most dramatic places on Earth, starting in Ethiopia.
