Environmental damage (especially acid rain and global warming) resulting from the burning of nonrenewable fossil fuels. However, investing in renewable energy is controversial for several reasons. First, not all scientists agree on the degree of environmental damage that can be attributed to fossil fuels. Second, fossil fuels are relatively abundant and cheap energy sources, and have contributed significantly to economic growth. Abandoning inexpensive fossil fuels for more expensive renewable ones will have major economic ramifications. Your students will enjoy analyzing this interesting and controversial topic. Learning Objectives After completing this unit, students will: 1. Learn to examine an energy/environmental issue using a five-step, decision-making model. 2. Explain basic facts about various renewable energy sources. 3. Identify the advantages and disadvantages of renewable energy sources. 4. Explain basic economic concepts used to analyze energy issues. 5. Understand that public policy decisions involve trade-offs among social goals. Unit Outline I. II. III.

The US population most closely represents a clumped pattern, as humans are social animals who interact regularly. The United States has higher populations near major cities, which generally have more resources than rural areas.
Animals get energy from food. Plant related food takes the sun to grow, and other prey may get energy from plants which uses the sun to grow. If you have any questions, don't hesitate to ask!
