Note: The Delinquents being sent to earth and the Culling were two parts of the same plan to increase oxygen levels enough so they would have time to fix the problem. The only change in this plan was that Abby convinced Jaha to hold off on the Culling for 10 days to at least give them some time to find out if earth was survivable. (Even then, based off the book, they would have technically had to wait 21 days to truly make sure the Delinquents could survive.)
