Renewable resource

A renewable resource (as opposed to a non-renewable resource, or finite resource) is a resource that can be obtained in unlimited quantities in Survival without exploiting glitches or using commands. While running completely out of resources is unlikely to be a factor in normal worlds due to the massive size of a Minecraft map, only some resources can be produced over and over without having to explore more terrain. Running out of resources can be a bigger issue on Superflat or Skyblock worlds, where resources are less plentiful, in PvP maps, where one would like to obtain resources without having to conquer more land, or simply if the accessible portion of the map is limited.

Most items dropped by animals or monsters are renewable because more mobs of the same kind can spawn and be killed again for more loot. The exceptions are drops of enemies that spawn just once with the generation of specific structures, such as elder guardians (only three spawn with each ocean monument). Drops of hostile mobs, with the exception of those obtainable by other means, are not renewable on Peaceful difficulty because the monsters do not spawn.

The renewable method to obtain a resource is not necessarily the easiest, fastest or safest, and may in some cases be highly impractical.
