  2. Key Concept 6.1- Science and the Environment • Rapid advances in science altered the understanding of the universe and the natural world and led to the development of new technologies. These changes enabled unprecedented population growth, which altered how humans interacted with the environment and threatened delicate ecological balances at local, regional, and global levels.

  3. Communication New modes of communication virtually eliminated the problem of geographic distance

  4. Transportation New modes of transportation virtually eliminated the problem of geographic distance

  5. New scientific paradigms transformed human understanding of the world

  6. The Theory of Relativity • http://www.youtube.com/watch?v=fEZupmpTcOU

  7. Quantum Mechanics • http://www.ted.com/talks/aaron_o_connell_making_sense_of_a_visible_quantum_object.html

  8. Big Bang Theory • Galileo and Copernicus were sort of right, but it’s not that simple. • … and we are sort of insignificant

  9. Psychology • We can even scientifically study how the brain works.

  10. Paradigm Shift • So how did new scientific paradigms transform human understanding of the world? • Which of these ideas had the biggest impact? Why?

  11. Green Revolution • Post WWII population explosion • Lots of babies • Smallpox eradicated • New technology/sanitation decreased malaria, cholera, typhoid, tuberculosis, and plague • Medical innovations: polio vaccine, antibiotics, artificial heart • Economists project world food shortages by the 70’s

  12. Green Revolution • Technology to the rescue! • GMO crops • Chemical fertilizers • Major increase in productivity • BUT… • Huge profits • IMF involvement • Pollution- waterways • Decline in crop diversity

  13. Energy Technology • Oil • Everyone buys a car • People like to buy more and more stuff that needs transportation • Oil got big. Really big. • Politics in Middle East and Africa • Global warming • Nuclear- after the bomb, what else can we use this energy for?

  14. Competition over resources • What resources? • How does this compare to previous periods?
