Global Commons

I've been working on some writing which references the Global Commons. 

These are shared spaces which are for all humanity. 

They all have regulations and agreements limiting how they can be used, in an attempt to protect them from exploitation or actions which may slowly degrade them, or set precedents for future use. 

Elon Musk's Space X / Starlink satellites are already degrading Space and littering it with satellites for commercial gain.

What threats are there on the various Commons?
