The copper price is determined by demand and supply. Demand is expected to fall because of the perceived economic problems of China. Also, the hedge funds are beginning to lose interest in copper which not only reduced demand, the supply of copper will increase (admittedly on in the short run) as the hedge funds seek to unload/sell their copper positions.

Looking at the supply of copper, there are numerous small copper mines coming onto the market which has to have some impact (supply side) on the copper price. Having a look at some of the major suppliers, RTZ has a number of very big projects coming on stream soon. And it's the same for Glencore and Anglo American.

So people will always need copper, the problem is that demand and supply for copper are falling which IS leading to a falling copper price. Maybe you should buy some share in a diamond exploration company?!
