1. Use CES to plot the Annual world production of materials against their Price. What trend is visible?

2. Make a plot of the static index of exhaustion for metals (the reserves in metric tons divided by the annual production rate in metric tons per year), using the “Advanced” facility in CES to plot the ratio. Which metals have the longest apparent resource life? Why is this index not a reliable measure of the true resource life of the metal?
