This document provides a sustainability review sheet with questions about key sustainability concepts such as the greenhouse effect, climate change, carbon sinks, ecological footprints, water consumption and pollution, waste generation and minimization, and the different impacts of climate change felt by developed and developing nations. Students are asked to define terms, list actions to reduce emissions and water usage, and identify reasons for future water shortages and ways to minimize individual ecological footprints. They are also prompted to consider perspectives on responsibility for waste and opinions on statements about water usage and climate change impacts on different countries.
