Wasn't quite sure where to ask the question in the title, or if this is even the right question to ask, but figured a Solarpunk community would be most likely to have the answers I'm looking for...

My reasoning is we are facing some global problems here, you know with all the climate change and whatnot; So we need global solutions for them; Therefore the obvious solution seems to be the United Nations 2.0, or League of Nations 3.0 if you will. Basically a global constitutional assembly, hopefully before it all devolves into total war again this time, or worse.

So I want to read up on what thought or maybe even activism there is out there specifically in this regard. Anything to read, recent or historic, you can recommend?

Any thoughts you want to share? Why can or can't this work? Am I being to naive here? Explain it Like I am 5 please!
