When I was a kid I had the bright idea during a daydream that if I were to officially acquire Antarctica as territory, either as part of my current country or as a brand new country, I could make the claim that air pollution from other wealthy nations is causing me to lose territory (glaciers melting from climate change). Then, I can fight back against other countries for their inaction towards climate change.

Other idea, build massive communities under the ice and snow in Antarctica, utilizing primarily wind energy above the surface for electricity.
