Forests

   2019    Nature    HD
The last episode examines the fragile interdependence that exists between forests' wide variety of residents, including bald eagles, hunting dogs and Siberian tigers.
Over half of all the world's trees, evergreen and deciduous, stand in great assemblies. For many of us, they are places of mystery and darkness. They are key to our climate, and home to countless unique species. The boreal forest contains 750 billion trees, and it stores over 40 percent of the world's carbon, making it a vital element in the fight against climate change. In the past, we have destroyed them without hesitation. Yet, forests do have an astonishing ability to recover. If we choose to give forests time and space, they could reclothe the earth with much of the rich and varied communities of animals and plants of which we have, so recently, robbed it. A future with more forests is key to the resilience of our planet.

Fresh Water

   2019    Nature    HD
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.

Prehistoric Worlds

   2020    Science    HD
Five times, the Earth has faced apocalyptic events. Cataclysms that have swept away all life forms, or almost. Each time, a handful of species has survived, establishing a new world. What did these prehistoric worlds look like? What catastrophes led to their disappearance? How did our distant ancestors manage to survive the five mass extinctions that the Earth has suffered, finally giving rise to the world we know today?
Combining CGI of ancient animal and plant life, VFX and filming, 'Prehistoric Worlds' looks back at the five mass extinctions of life on Earth that allowed the advent of the human race. On the brink of a sixth mass extinction that the scientific community considers imminent – this time caused by mankind – this film gives us an interesting and powerful look at Man's existence on the scale of the history of our planet.

Vavilov

   2020    Nature
The fourth episode sees host Neil deGrasse Tyson exploring our eternal quest to end hunger and honoring Nikolai Ivanovic Vavilov, pioneer of modern plant breeding, who risked his life for a discovery that would change the history of science. Vavilov's story is marked by both the tenacity and creativity and is particularly tragic. Interwoven into Vavilov's somber narrative are warnings and treatments of science and its ethical implications, especially when science itself comes under attack from political forces.
