Energy Resources TypesBenefitsTrade-Offs Fossil FuelsCoal Natural Gas AlternativesNuclear RenewablesHydroelectric Wind Solar OtherGeothermal

Energy Resources Alternatives Types – Nuclear & Hydroelectric Benefits – Reduced greenhouse emissions Trade-Offs – Nuclear - Accident risk, Hydro - disrupt flows & ecosystems, displace ppl Three Gorges Dam, China

Energy Resources Renewable Energies Types – Wind & Solar Power Benefits – Safe & environmentally friendly Trade-Offs – Cost & feasibility In the Works Geothermal & Hydrogen Energy Fusion Power

T-P-S How are population, consumption, and technological advances related to environmental impact?

Development & The Environment Population Growth 6.7 b ppl (80m/yr) Developing countries Death rates ↓ Agricultural techniques = more food production How does population growth affect the environment?

Development & The Environment Consumption How does consumption affect the environment? ~18 % of pop. consumes over 50% worlds resources Resource scarcity = conflict What is sustainable development? Meet present needs w/out depleting for future

Closure What do you think is meant by the term “environmental equity”? Fair access to clean air, water, and soil regardless of economic or social status.

Potential Thesis Topics How a certain environmental problem has contributed to instability in a country or region. Impact of human activity on certain environment (Amazon Basin – dams & deforestation, desertification of Sahel, Three Gorges dam in China) How environmental issues are connected to international security. The (in)effectiveness of international agreements. Successes or failures in international cooperation on the environment. Controversy surrounding the Kyoto Protocol. The legitimacy of climate change. The potential for sustainable development. Viability of alternative energy resource. Controversy surrounding GMOs & biosafety. Role of foreign aid in developing nations. Causes or prevention of major diseases (AIDS in Africa/China, TB, Malaria, Cholera) and pandemics Link between pandemics and globalization. Solutions for Flooding in Pakistan or Cholera in Haiti
