What makes an object or substance a resource?

An object or substance is classified as a resource only when it has utility — the capacity to satisfy a human want or need. Utility, not the physical handling of the material, is what confers resource status on it.

Here, an object or substance becomes a resource specifically because of its utility or usability. Processes such as purification, extraction, or discovery can change how accessible or refined a material is, but none of them is, by itself, the defining quality that makes something a resource — that role belongs to utility alone.

Consider each of the other processes on its own:

• Purification can make a substance cleaner or more refined, but its status as a resource still depends on whether it serves a need, not on how pure it is.

• Extraction can bring a substance within people's reach, but it does not by itself decide whether the substance is useful — a substance can be extracted and still have no use, or already be useful before it is extracted.

• Discovery of an object only means people have become aware that it exists; awareness by itself does not establish whether the object can meet a need.

So the quality that actually makes an object or substance a resource is its utility or usability.
