Questions 1–6

1. In 2008, it was estimated that there were 5.6 million metric tons of recoverable reserves of tin. There are about 10.1 million metric tons that are not as easily recovered. The production rate of tin is about 0.333 million metric tons per year. What is the projected lifetime of tin?

1. As tin and other ores become scarcer, what will happen to the price of these commodities?

1. As a result of increasing prices, what will happen to the part of the tin resource that is not currently economically valuable enough to mine?

1. How would an improved mining technique or technology influence the quantity and cost of mining the reserves?

1. What is likely to happen if we run out of a resource or if its quantity drops to a very low amount? Think about its use and what could be done about its shortage, economics, price, and mining. Might there be environmental consequences?

1. Petroleum production in the United States peaked in the 1970s and now much of our petroleum comes from nations that are not necessarily very friendly. How has petroleum production in the U.S. become a political issue, and what are the two sides? What are the consequences of unbridled mining of petroleum? What are the consequences if petroleum is not mined?
