  5. 5. Hawksbill
  6. 6. Leatherback
  7. 7. Olive Ridley
  8. 8. Flat back</li></li></ul><li>Their Lifestyle<br /><ul><li>Nesting Season May 1st and October 1st
  9. 9. They lay 100-150 eggs at a time.</li></li></ul><li>Light Pollution and Collisions<br />Artificial lights disorient babies.<br />Predators already make it difficult to make it to sea.<br />Increase human activity in the water can cause potential boat collisions.<br />
  10. 10. Debris and Pollution<br /><ul><li> Oil formulates tar in places where plankton thrives (the food for hatchlings).
  11. 11. 6% of Sea Turtle deaths in the US is from oil ingestion.</li></ul>Turtles can eat anything that looks like food such as: plastic bag, balloons, bottles, rope, and fishing line.<br />
  12. 12. Fibropappilloma Virus CutaneousFibropapillomatosis<br />
  13. 13. Hunting<br /><ul><li>Sea Turtle meat is used for food and an aphrodisiac.
  14. 14. Skin and Shell is used for boots, shoes, and handbags
  15. 15. Bones can be used for tools and art.</li></li></ul><li>Fishing<br />Shrimp Trawl nets are the leading cause of deaths<br />Gill nets are the second leading cause.<br />
  16. 16. Nesting Incentive<br />Watamu Turtle Watch<br />Madagascar paid collectors<br />Incentive Programs all around the globe<br />Tanzania, Nicaragua, & Solomon Islands<br />Solutions<br />
  17. 17. Minimizing Light Pollution<br />Turn off lamps<br />Tint windows <br />Install motion detection lights<br />Solutions<br />
  18. 18. The Fishing Industry<br />Policymakers can use their jurisdiction<br />Put laws in place for marine conservation<br />Monitoring<br />Solutions<br />
  19. 19. By-Catch prevention<br />Change when and how lines are set<br />Smaller hooks<br />Turtle Excluder Devices<br />Solutions<br />
