Environmental advocates and other opponents of the Rosemont Copper Mine need to take a self study course on the importance of copper in modern civilization. It's an easy one step course.

Extra credit. Explain in one sentence how solar and wind energy is transmitted to homes and businesses. Think hard. There's one word you can't exclude.
PhD candidate. How much copper is used in a typical gasoline powered car? If you said 55 pounds, you're right! How about a hybrid? 110 pounds. Now, how about an all electric vehicle? 220 pounds. If you answered all three correctly, you are now entitled to be addressed as Doctor of Copper.
