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.

Bora Bora is the most popular destination in French Polynesia, certainly because of its lagoon, considered the most beautiful lagoon in the world. In this context, the islet could have sunk under concrete and pollution, and the reef could have been irreparably impacted. However, thanks to the will of a handful of inhabitants including the mayor of the island, Bora Bora is today a model of sustainable development, with water treatment technologies that are 15 years ahead of France, programs to rebuild corals and protect wildlife, educational actions and the rehabilitation of Polynesian traditions such as “rahui” and the establishment of a monitoring network using new technologies. All of this makes the island a veritable open-air laboratory that shows the way for all tropical coastal environments around the world.
