luxury space tourists sending them a check to turn the moon into their personal graveyard, polluting the surface with organic material which seems scientifically disastrous dictates the efforts just fine.
If the only thing that stands between turning the moon into the next dumping ground is the traditions of the Navajo people they might be worth listening to.
Not sure why people are trying to create a wedge between science and religion here. The Navajo and scientists have more in common on the question of stewardship of the moon than SpaceBurials Incorporated. Same goes for stewardship of the earrh btw.
