How is the decline in ocean fisheries considered an example of the "tragedy of the commons"?
What will be an ideal response?
The decline in ocean fisheries are considered an example of the "tragedy of the commons" because fish is substantially a common resource, but there is no infinite amount. If humans fish too much to the extent of an extinction of all types of fishes, we are left without the resource of fishes that are used for many things—for example, protein.
