How does the decline in world fisheries represent a tragedy of the commons?
Overharvesting of fish has had a detrimental impact on the environment, making it less productive and unable to recover.
The tragedy of the commons refers to permitting livestock to graze on open land - overgrazing of this land caused the plants to die off, the soil to erode and the region to suffer from the lack of grazing space.
As worldwide economies continue to extract fish using sophisticated techniques, the populations of these fish stocks have dwindled, resulting in an environment (much like the commons) that is inherently less productive and unlikely to recover. the main cause of this is many different groups of people are exploiting these resources for short term gain and sacrificing the long-term sustainability of the resource./
