Scars of Growth (2024)
The Green Deal, Europe’s new growth strategy, is Brussels' recipe to save the planet from climate collapse. With electric cars and renewables, the EU believes it can promote economic growth while protecting the planet. Is that possible? Green technologies require many critical metals that are supplied mainly by China. To reduce dependencies, politicians are in favor of reopening “green” mines in Europe. But people living in the areas are worried that their lives will be sacrificed for the energy transition. This is the case of Hector, a Spanish farmer, and Matti and Karin Niia, two Swedish reindeer herders. They are determined to fight against these projects that threaten their way of life. While the industry is lobbying for the adoption of an EU law on critical raw materials to facilitate the opening of new mines, Diego, from an environmental NGO, travels across Europe to investigate whether mining can ever be truly sustainable.
