3D Earth will no longer be inhabitable?

Ra also says that in early 4th density there often isn't yet a desire to serve. It is just barely 51% after all.

Can you provide a reference for that quote?

66.7 Questioner: What about the ones with the dual, not the Wanderers but the harvested and dual-activated third- and fourth-density bodies entities? Are they able to heal using the techniques that we have discussed?

Ra: I am Ra. In many cases this is so, but as beginners of fourth density, the desire may not be present.

However this is not about desire to serve, but a specific practice - spiritual healing.
