What is the point of arguing who owns what? Does that refute the idea that people who are most directly affected should have a greater say?

Also the world hardly operates according to that concept of owning that you mention with regards to environmental protection. Is the international community pledging resources to support countries that choose to protect the environment instead of seeking so-called economic development? See for example this https://en.wikipedia.org/wiki/Yasuní-ITT_Initiative
