Why wouldn’t the wraith try to “farm” humans?
The wraith depend on the human population of the Pegasus Galaxy to satisfy their feeding requiremnents. They allow human populations to grow until a point at which they can be culled, leaving behind a sufficient group to allow for population growth in the future. By the team the Atlantis expedition arrives to Pegasus, the wraith have grown in numbers to the point that the human population is not able to sustain them and they must “sleep” internittently to allow for human reproduction. When they learn that the Milky Way galaxy hosts human populations that have grown unchecked, the wraith make a desperate attempt to reach this “new feeding ground.”
It seems well within the scope of wraith science and motive to farm humans in captivity and increase their numbers rather than allowing the population to grow naturally. Even if they didn’t literally breed humans, methods like IVF could also be an option.
In the thousands of years the wraith have existed, it seems like this would have been an optioned they should have explored early on. It would be a darker plot plot line which is maybe why the producers avoided this. Curious if anyone had any other thoughts or if I missed something.
