3. Top 10 threats to the Sustainability of the Human Civilization 10. Paris Hilton on the road (summer 2007) 9. Over/under population- low risk now, most model predict sustainable population 8. Global warming/Climate change- low risk now, uncertainty high. time scale for irreversible damage is long 7. Ozone layer depletion- under control after banning freones 6. Alien invasion- risk uncertain -students’ idea 5. Religion and Politics- global terrorism and local wars-not reversing progress -just slowing down 4. Pandemic diseases- been confined in the past (AIDS, Ebola, Bird Flu, Flu 1918) 3. Collision with an asteroid- risk low?-moderate uncertainty in risk and timeline, potentially preventable. 2. Nuclear Holocaust- comprehensive nuclear weapons ban 1. End of fossil fuels- solution??? Energy Consumption: 1998: World total: 12.8 TW ( 1 TW= 1012 W) 2050: World total: 30 TW 30% from oil, 80% from all fossil fuels Currently, only a small fraction comes from renewable resources With the current known oil reserves and the current rate of oil consumption there will be no oil left on this planet by 2100 (peak of oil production in 2015-2030)

4. World Energy Demand Energy consumption predicted to increase 56% from 2010-2040 http://www.kip.zcu.cz/kursy/svt/erasmus/8_2_ENERGY.html Require 30-40 TW to support >10 billion by 2050
