Which of the following is NOT considered a part of Global Commons?

Rivers

The areas or regions of the world which are located outside the sovereign jurisdiction of any one state, and therefore require common governance by the international community.
These are known as res communis humanitatis or global commons. Global commons include the earth's shared natural resources. They include the Earth’s atmosphere, Antarctica, the ocean floor, and outer space.

River is a domestic or inter-state issue rather than a globally common issue.
