The Antarctic wall is the edge of our known world on a flat Earth map, which is also the UN logo.
The last man to explore Antarctica before the Antarctic treaty was admiral E. Byrd who said it was an untouched reservoir of natural resources.

But to answer your question more directly, what do all these 50 countries who signed the treaty have in common?
They want to control and enslave their populations.
As a slave master if you had the ability to give your people free and endless energy, would you do it - obviously you're not incentivized to - you'd want your people to have the least free time possible, so they can't figure out how badly you're fucking them up the ass.
You need a nation of workers, not a nation of thinkers.
If food, water, energy and land is practically free and abundant, you're gonna have a tough time as a dictator.
Bitcoin broke this enslavement system, but most people don't know this yet.
Not hating, just curious… Why would the earth be flat? Did god create it that way? Or did it naturally occur? Is there any evidence of other flat planets/worlds? As per your diagram, why can’t Australia see the sun during the night? How does gravity work?
