Aleading environmental group recently published a report contending that humans are running a "resource deficit" because we are using natural resources faster than they can be regenerated. the group claims that this means that economic growth will eventually stop, and will even be reversed. an economist would?

Propose a sustainable development policy

Explanation:

Running a resource deficit which means that using natural resources faster than they can be regenerated would affect the economic growth of any country.

An economist in this case would propose sustainable development policies which would ensure that the current generation does not use up the resource available. Policy that would limit the use of non renewable resource would be proposed. Policy that would ensure alternative resource so as to ensure diversity and use up existing resources. All these policies must ensure that economic growth does not decline but keeps increasing.
