Question 18

Read the following scenario and answer the questions below.
In 2010, geologists working for the U.S. military operations in Afghanistan discovered a literal treasure- trove of mineral deposits with a preliminary estimated value at nearly U.S. $1 trillion. So far, no proposals have been made for extracting these resources, but already parallels have been drawn to the many dimensions of human rights issues that have plagued coltan production in the Congo, oil drilling in Nigeria, and the "blood diamonds" of Sierra Leone.
You have been appointed as a delegate to the U.N.- initiated Afghan Minerals Development Council, which will convene in the next few months. The goals of the council are to oversee the extraction and export of resources and to ensure economic benefits, social and environmental justice, as well as environmental protection for the Afghan people.
