Space Travel Will Save the Planet

  1. 1. Space Travel Will Save The Planet<br />or<br />Black is the new Green.<br />
  2. 2. Problem: People Reproduce<br />There are a LOT of people.<br />One of people’s favorite things to do is to make more people.<br />
  3. 3. Problem: People Consume<br />Everyone likes to be comfortable.<br />People don’t want to give things up.<br />
  4. 4.
  5. 5. Problem: Resources are Finite<br />We don’t have unlimited energy (yet)<br />We don’t have unlimited room.<br />
  6. 6. Myth: “Sustainable Growth”<br />There is NO SUCH THING as global sustainable growth!<br />We only have so much stuff!<br />We can be sustainable, but not grow; or grow and not be sustainable.<br />
  7. 7. Population - The Original Hockey Stick<br />It’s exponential, baby!<br />
  8. 8. It’s Never Been a Problem Before…<br />How have we managed to grow?<br />It hasn’t been sustainable.<br />Technology has made it possible.<br />
  9. 9. O RLY?<br />
  10. 10. Our own worst enemy…<br />In 2005, global carbon emissions were 29 billion metric tons.<br />Since then, we’ve added 363 million people.<br />That’s another 1.6 billion metric tons of carbon.<br />
  11. 11. One of these every 5 years.<br />
  12. 12. It gets worse…<br />If everyone consumed as much as the US did…<br />Carbon emissions would be at 134 billion tons/year.<br />Yeah, that’s not going to work for long…<br />
  13. 13. What Are Our Options?<br />Decrease consumption to match growth.<br />Right, that’ll work.<br />Stop making more people.<br />Doesn’t seem very likely.<br />Door #3? (goat not included)<br />
  14. 14. Leaving the Cradle<br />There’s a LOT of room in space.<br />There’s a LOT of energy in space.<br />This sounds promising…<br />
  15. 15. Benefits of Space Travel <br />Water Filters, Smoke Detectors, Cordless Drills<br />Lots of other technology<br />It’s hard to predict what will come out of an investment in space.<br />Could you have predicted the Internet?<br />If so, do you want to start a company?<br />
  16. 16. More Benefits<br />Colonies need to be sustainable.<br />Reusing water, soil, air<br />Energy efficient<br />Maybe we could use this on Earth, too?<br />Better solar panels<br />Better soil/water reclamation<br />
  17. 17. It’s Sustainable!<br />Offset population growth by emigration off-planet.<br />More resources to support a larger population<br />Abundant energy (THE SUN!)<br />Fewer anthropogenic environmental concerns.<br />
  18. 18. Colonies, or Off-site Backup<br />Off-planet colonies decrease the chance of us going the way of the dinosaurs.<br />Even if we do something phenomenally stupid…<br />
  19. 19. One small step…<br />We have the technology<br />Well, some of it.<br />Space Stations<br />We’ve got one already, we need more, lots more.<br />Rocket Ships<br />More X-Prizes!<br />Robots<br />We always need robots.<br />
  20. 20. Quick Recap<br />We’re running out of EVERYTHING (except people)<br />Sending ONE person into space saves 20 tons of carbon/year.<br />Space-related technologies are AWESOME<br />Space exploration is sustainable<br />
  21. 21. What can you do?<br />Tell your kids to be astronauts!<br />
