Everything we can touch, feel, breathe or burn is an element or compound. Everything built, manufactured, or invented relies on an inexorable causal relationship commencing with the extraction, transportation, storage, and distribution of elements.
Over the course of 6,000 years, scientists have classified 92 unique natural elements on our planet. These elements have different physical properties and relative rarity in the earth.
Extracting elements requires an input of energy, labour, time, and information (input units).
