This bilingual activity guide helps to develop students' understandings of the interdependence of people and the environment. Interdisciplinary resources are provided featuring environmental education lessons with applications to the social studies, science, math, and family life education curricula. It is designed for the middle school level, but the activities can be scaled up or down for use by students of various ages, including adults. The reading and activities in this guidebook are designed to broaden students' knowledge of trends and connections between population change, natural resource use, gender equity, and quality of life issues for individuals and communities. This knowledge, combined with critical thinking skills developed in each activity, will help students explore their roles as global citizens and environmental stewards. Topics and activities are divided into three sections: "Understanding Population Dynamics"; "Reflecting on Resources"; and "Making Connections." Extensive references and other resources are provided and suggested. In addition to a glossary, there are numerous, charts, diagrams, and figures provided throughout the text. (KFT)
