  2. Case History: Easter Island • A small volcanic island with a subtropical climate • By the 16th century, a thriving society with 15,000–30,000 people • Europeans reached there in 17th century, only 2000 people struggling in a degraded environment • Reasons for collapsed society: overpopulated, deforestation, soil erosion, loss of agricultural base, further conflicts and wars, geographic isolation, and geologic limitations

  3. Looking Ahead: Earth • Earth: geospatially isolated in the universe • Population explosion: exponential growth • Facing limited resources: energy, soil, fresh water, forests, ocean fisheries, rangelands • Global environment: conflicts and integrated resolutions • Lessons from Easter Island: aware of limited resources and needs for sustainable global economy
