On 1500 metres above sea level, on the slope of the mountain Hallingskarvet, stands "Tvergastein', the cabin of Norwegian philosopher Arne Naess. In his life he has spent nearly 12 years in this hut, where he wrote several books and essays on philosophy and ecology. In this film, Naess tells about the concept of 'deep ecology', which was first introduced by him in 1973. One of the basic tenets of deep ecology is that nature has a value in itself, apart from its possible use value to humans. Next to being a famous mountaineer, Naess has been a longtime activist in the environmental movement. He gives an inspiring account of his participation in blockades to prevent the Alta river in northern Norway (the area of the Sami, an indigenous people) from being dammed.

In the cobalt mining areas of Katanga in the Democratic Republic of the Congo (DRC), babies are being born with horrific birth defects. Scientists and doctors are finding increasing evidence of environmental pollution from industrial mining which, they believe, may be the cause of a range of malformations from cleft palate to some so serious the baby is stillborn. More than 60% of the world’s reserves of cobalt are in the DRC and this mineral is essential for the production of electric car batteries, which may be the key to reducing carbon emissions and to slowing climate change. In The Cost of Cobalt we meet the doctors treating the children affected and the scientists who are measuring the pollution. Cobalt may be part of the global solution to climate change, but is it right that Congo’s next generation pay the price with their health? Many are hoping that the more the world understands their plight, the more pressure will be put on the industry here to clean up its act.

Living in an ancient redwood tree for more than two years to prevent the tree from being clear-cut, Julia Butterfly Hill captured our hearts and minds by showing us that one person can make a difference. Through interviews with Hill, filmmaker Doug Wolens paints a portrait of an intensely spiritual and articulate woman who encountered both beauty and horror (she was assaulted by lumber company helicopters at one point) during her time above ground.

Western views and the legal system tend to view nature as property, and as a resource from which wealth is extracted, a commodity whose only value is to provide for human needs. But for millennia indigenous communities have viewed themselves as part of nature.

Named for the man many consider the father of the modern environmental movement, the David Brower Center was founded on the idea that when diverse people engage, dream, and work together, they are more effective at finding solutions to today’s most pressing environmental and social problems.

How can we prevent epidemics? Why do viruses and bacteria move? Rather than trying to contain epidemics one after another, why not stop the processes that encourage their emergence? The challenges are enormous, but scientists argue that solutions exist. Because if emerging diseases are the collateral consequences of our lifestyles, our lifestyles are under our control.

The climate crisis, Germany’s nuclear phase-out and Russia’s war against Ukraine are just three of the heavy pieces in the dramatic game about the future of energy. Caught in the middle are two small towns with barely a thousand residents each: Gundremmingen in Bavaria, home to a shuttered nuclear plant, and Choczewo on Poland’s Baltic coast, where the country’s first facility is now under construction. What do the good people on the ground think about it all?
