Earth's Copper Supply Inadequate For Development?

ScentCone writes "Pennies, pipes, untold miles of CAT5 - they tie up a lot of copper. Unlike abundant iron and aluminum, copper is relatively scarce. But it's vital to electricity generation/transmission, plumbing, and other uses central to a modern standard of living. Scientific American is providing a quick overview of the situation. They report the conclusion that there simply isn't enough available. Canada, Mexico and the US average 170kg of copper use per person, and the most generous estimates suggest that only 1.6 billion unused metric tons exist. More reclamation and use of fiber, wireless, and PVC helps - but won't be enough to cover the billions of people who don't yet live in highly wired/mechanized societies."

Indentured Childhood

When I was a kid, my dad made me spend hour after hour knocking the cores out of laminated transformers with a 15 lb. sledge so that the copper wire was free.

I also had to sit and cut the plastic off of foot after foot of copper wire with a utility knife and leather gloves so we could recycle the copper wire for cash.

At last, I can now put these valuable skills on my résumé! I just hope my career in technology doesn't come around full circle ...

Re:Pennies are not copper anymore

One of my insider mining newsletters that I subscribe to just mentioned how zinc might end up being the most rare material in the coming years. One guy said that pennies made before 1971 are worth more than 1c in copper, and that the newer pennies might soon be worth much more than 1c due to their high zinc content.

Time to horde pennies maybe.

Not Enough?

Seems to me that at 170Kg a head, 1.6 billion tons is enough to support 9.6 billion people. At the standards to which we in North America have become accustomed. So, where exactly is the shortage?
