Editing Resource depletion (section)

=== Issues  ===
Depletion accounting is complex to implement as nature is not as quantifiable as cars, houses, or bread.<ref name=":9" /> For depletion accounting to work, appropriate units of natural resources must be established so that natural resources can be viable in the market economy. The main issues that arise when trying to do so are, determining a suitable unit of account, deciding how to deal with the "collective" nature of a complete ecosystem, delineating the borderline of the ecosystem, and defining the extent of possible duplication when the resource interacts in more than one ecosystem.<ref name=":9" /> Some economists want to include measurement of the benefits arising from public goods provided by nature, but currently there are no market indicators of value.<ref name=":9" /> Globally, [[environmental economics]] has not been able to provide a consensus of measurement units of nature's services.
