Review What are the three strategic environmental themes emphasized by Wright? –Sustainability –Stewardship –Sound Science What are the three integrative environmental themes emphasized by Wright? –Ecosystem capital –Policy and Politics –Globalization

Review What is sustainability? –Definition –Five components Ecosystems use sunlight as their main source of energy Ecosystems are built upon interrelationships not independence Ecosystems dispose of wastes and replenish nutrients by recycling Ecosystems, regulate the size of member populations Ecosystems, maintain (bio)diversity

Review What is sound science? –Data –Shaping principles –Theories

Questions about energy? Where does energy come from? How does energy work? What are our major sources of energy? How is energy produced? Do we have an energy crisis?
