Can art address ecology? Ecological questions are omnipresent in today's art. Themes such as climate change and the biosphere dominate the exhibition scene. Recycling as an artistic method, the avoidance of environmentally harmful materials, and the reconciliation of art and nature are ever-present in the younger generation. We are experiencing a profound transformation. As art history shows, art can raise awareness and develop new relationships with nature. How was this evident during the Renaissance, with Leonardo da Vinci, the Romantic period, Impressionism, the early modernism of the 20th century, and the Land Art of the 1970s? And: Can art help repair the planet? The text is accompanied by about 50 essential works addressing these questions from both the past and present.
