Russia does not seem to agree with you concerning the scarcity of Antarctic resources, and has indicated a keen interest in developing Antarctica when the treaty prohibiting it expires.
The reason for moving large populations to Antarctica would be the same as the reasons for the construction of Norilsk: To support various extractive industries.
I did not, anywhere, propose that Antarctica be settle for lack of living space elsewhere. Where in my article did you see that? I’m very confused. Of course that wouldn’t make any sense, which is why I never said any such thing.
Why should we desalinate the oceans by the by? Wouldn’t that kill nearly everything living in them?
