This is a poster issued in English, French, and Spanish by Education for Sustainable Development (ESD), a UNESCO agency established in the early 1990s in response to the urgent environmental challenges facing the planet. It aims to foster the implementation of sustainable development through education, training, and public understanding, giving governments, educators, and learners of all ages the skills and reliable data to take action. A series of six detailed images in green on black suggest the innate connection between human activities and the state of the environment.
