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.

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.

The written word is so important in everyday life that there can be few more radical acts than forcing an entire nation to learn a new script. Yet that is what happened in Turkey in 1928 when Mustafa Kemal decreed that the Arabic script would be replaced by the letters of the Latin alphabet. Communication with computers using human language is usually made with Latin letters. This is how most Chinese people interact with their computers and smart phones, using a Latin-based phonetic script called Pinyin. As a result, even highly educated Chinese are losing the ability to write using Chinese characters. Could what is happening in China be the future of writing everywhere?
