This document provides a housing toolkit for residents focused on environmental sustainability. It covers four main topics: food sustainability, water sustainability, energy sustainability, and recycling/waste sustainability. For each topic, it discusses what the issue is and why it matters, provides a film list related to the topic, suggests discussion questions, and lists activities. For food sustainability specifically, it defines the concept, explains its importance, and gives details on film options, sample discussion steps and questions, and tips for reducing an individual's carbon footprint from food. The overall goal is to educate residents and encourage environmentally-friendly behaviors around these sustainability issues.
