An overly dramatic article in a recent issue of the New Yorker talked about the coming worldwide sand shortage. Using some anecdotes and selective statistics the author was able to weave a tail about the "Sandpocalypse." Meanwhile, the world continues to move on. Natural resources are finite, but it is worth noting that the surface of the planet is composed mostly of water and rocks. The rocks turn into sand naturally, but if you're in a big hurry and have the right equipment we can make sand directly from rocks--much like we can make electricity directly from the sun. Granted, this is more expensive than just digging it out of the ground, but expensive products and services tend to create competitive production environments.
The earth has plenty of resources. In fact, the one resource that exhibits frequent scarcity is human intelligence.
