IB Environmental Systems and Societies is a trans disciplinary subject, a college-level introduction to ecology. It is science applied to ideas presented in geography, economics, and TOK. We’ll look at the ways different people around the world perceive and respond to various environmental issues, and we’ll dig deeper into their experiences and motivations for taking action (or not taking action).

ESS covers eight major topics: foundations of the course and its major ideas, ecosystem structure and function, biodiversity, water resources, soil systems and food production, atmospheric science, climate change and energy production, and the interaction between human populations and resource use.
