The problems facing our planet, such as environmental degradation, climate change, dwindling resources and global inequality, are nothing new to us, and yet we continue to pursue our wasteful lifestyles. Is design responsible for these problems if it encourages mass consumption with ever new products and trends? How can design help put an end to the destructive exploitation of our planet? This film showcases designers who experiment with unusual materials, such as seaweed and fungi, study energy-saving production methods in interdisciplinary teams and ask critical questions about the responsibility designers have for their products and production methods. A return to critical approaches to design in the 20th century shows how design theorist and educator Viktor Papanek, who was an advocate of politically responsible design, is experiencing a revival and inspiring many contemporary designers. Julia Lohmann builds installations and objects from seaweed. Marjan van Aubel wants to achieve a "solar democracy" with equipment and buildings that generate their own power. And in their "Superflux" laboratory, British designer and artist duo Anab Jain and Jon Ardern speculate about our possible future, when climate change will make Earth barely habitable.
