Minecraft wiki entry for Non-renewable_resource, associated text: A non-renewable resource (as opposed to a renewable resource) is a resource that cannot be obtained in indefinite quantities in Survival without exploring more terrain or using certain glitches, commands or Creative mode to create more of them. While running out of resources other than the unique dragon egg is not likely to be a factor in normal gameplay due to massive size of a Minecraft map, in principle there is a finite quantity of these resources available in each Minecraft world.
