This material is designed both for quantitative and sustainability education. Everything is based on real world data like population, energy use, or GDP. The presentation requires familiarity with percent calculation. Most problems and case studies in the tutorial are suitable for class discussion. Some are suitable for advanced students (e.g. AP calculus).
