Mariam Kasali is an Environmental Health Sciences student at the University of Ibadan, where she studies how environmental factors affect human health. Her interest in planetary health stems from her background growing up in one of the largest slums in Lagos, Nigeria. After completing multiple courses on planetary health and climate change, she came to realize that public health cannot be separated from the planet we inhabit. This has led her to participate in several leadership roles and volunteering activities involving climate education and environmental awareness to foster a world where everyone is enlightened and no one is left behind.
