Just to show that the misinformation goes both ways, the belief that we are running out out of resources is completely misplaced, at least as far as mineral sources are concerned. There exists a notable difference between reserves and resources.
A reserve is that which is economically viable for extraction. There are vast pockets of resources scattered throughout the crust that simply cannot be accessed with current technology. They are not yet reserves and are not considered in the stats typically published. For example, the deepest coal mine is roughly only 600 meters deep and most abandoned oil fields have only been half drained. The more they are depleted, the less cost effective pumping becomes, so the company moves on. As the prices of resources increase, the number of reserves will also increase.
But still, this is of course a dead end street. Just because we are not running out does not mean we shouldn't radically rethink our archaic energy model. Current life will be eradicated long before natural resources are depleted...we are killing ourselves through pollution and disease and destroying the processes which created us and continue to sustain us. And regardless of what side of human-induced global warming one sympathizes with, rising ocean levels will begin to threaten the coasts and displace a huge portion of the population. Earth may be responding as an attempt to counteract our own ignorance, destroying the cancer we have been tending to.
