A more thorough explanation:

COMMUNIA

Communia (pronounced kuh-myoo-nee-uh) is a Latin term that refers to things that are owned in common by everyone. This includes things like running water, the air we breathe, and the sea.

• Running water in a river or stream is an example of communia. No one person or group can claim ownership of the water, as it is a natural resource that belongs to everyone.
• The air we breathe is also considered communia. No one person or group can claim ownership of the air, as it is a shared resource that is necessary for all living things to survive.
• The sea is another example of communia. While some countries may claim certain portions of the ocean as their own, the sea as a whole is considered a shared resource that belongs to everyone.

These examples illustrate the concept of communia by showing that certain resources are not owned by any one person or group, but rather are shared by all members of a community or society. This idea is important because it helps to ensure that everyone has access to essential resources, regardless of their social or economic status.
