So, basically Antarctica becomes exploitable. Is there any way it could be exploited for economic gain (what raw materials etc.? I recall oil...), military uses, etc. Is large scale colonisation really viable in such harsh conditions? What are the environmental drawbacks? Hypothetically, are Antarctic prison camps viable or just a waste of taxpayers' money/government funds?
Also, how is it likely to happen? Who has plans to do this sort of thing? Even without the treaty, is anyone really interested?
