Anuli,

On the one hand you are right, there is no increase in supply of land where as more silver get produced each year. The amount of land however does not get reduced where as the remaining amount of mineable silver get reduced each year. So there will always be land, but we will run out of silver because it is not 100% recycled. According to the usgs there is 280,000 tonnes of silver reserves and annual demand is about 22,000 tonnes, so we only have 13 years of proven supply left. Even perennial silver bears like Jessica Cross have predicted that silver demand is going to skyrocket because of its new health and solar energy applications. We will have a silver shortage before we have a land shortage.

the United States currently has 7 acres of land per person, but only produces 0.13 oz of silver per capita. Our silver demand is 0.60 oz per capita.
