Answer: A common resource
Explanation:
A common resource is any scarce resource, that gives users tangible benefits but which is not owned by anyone in particular and no one has exclusive claim to it. Common resources may include public spaces like parks or nature preserves or certain natural resources like fish in the sea.
A major concern with the common resources is overuse, especially in cases where there is poor social-management systems that are in place to safeguard the resource. The bluefin tuna is a common resource.
