Mavine is a Level IV medical student at the University of Nairobi with a Bachelor of Science (Honours) in Human Anatomy from the Intercalated Program. Long fascinated by space science, he has a strong grasp of the closed-ecosystem model used in space exploration—one that prioritizes sustainable life-support systems and the ethical, efficient use of limited resources under extreme conditions. These principles closely mirror the foundations of planetary health, which views Earth as a delicately balanced system shaped by the interaction of biotic and abiotic forces. Guided by the question, *how does the environment shape human biology, health, and survival?*, Mavine seeks to uncover adaptive survival patterns that can inform more sustainable ways of living as the world confronts present and future planetary crises.
