The manufacture of cell phones involve the use of several rare minerals that are primarily found in the Congo Basin of Africa. The mining of these has led to habitat destruction of endangered species and the death of millions due to political conflict. What is the most practical action to be taken in response to these facts?

A) Cell phones should be recycled so rare minerals can be recovered.
B) Mining should be monitored by the U. N. to minimize this destruction.
C) We should continue using older models of cell phones as long as possible.
D) Cell phones should be manufactured using more readily available materials.
