Martianism is a philosophical and cultural movement that explores the idea of life on Mars and the implications of potential human colonization of the planet. It encompasses various disciplines, including science fiction, environmental ethics, and space exploration, encouraging discussions about humanity's future in the cosmos. The movement often draws inspiration from works like Ray Bradbury's "The Martian Chronicles," which imagines human interactions with Martian life. Martianism also raises questions about the ethical responsibilities of humans as they venture into new worlds, emphasizing the need for sustainable practices and respect for any existing ecosystems.
