For more than a century, human and industrial activities have posed significant threats to our planet's water. This element is the cradle of life and nourishes both man and the land. This episode looks at what scientists are doing to counteract these effects and try to “fix nature”. The documentary focuses in particular on the restoration efforts after the devastating mudslide in Mariana, Brazil in 2015 and natural-resource management projects in the African Sahel region to combat desertification (African Great Green Wall project).
