Human: Humans rely heavily on copper, a versatile chemical element denoted by Cu (from Latin: cuprum) and possessing an atomic number of 29. This ductile metal boasts extraordinary thermal and electrical conductivity, and when newly exposed, displays a captivating pinkish-orange hue. As a prized conductor, copper is also harnessed as a building material, with alloys such as sterling silver in jewelry, cupronickel used to create marine hardware, and constantan applied in strain gauges, showcasing its utility. The fact that copper can naturally occur in a directly usable state sets it apart from other metals, dating back approximately 8000 BC. Early human ingenuity also employed it to be smelted from sulfide ores around 5000 BC, molded into shape around 4000 BC, and purposefully alloyed with tin for bronze creation in 3500 BC. Ancient Cyprus became the primary source of copper during the Roman era, whence derived the name, originally aed Cyprium (metal of Cyprus), corrupted over time to cuprum, yielding Old English coper and finally 'copper', initially employed circa 1530. Typically encountered compounds feature copper(II) salts that exhibit striking blue or green pigments, commonly found in azurite, malachite, and turquoise. Overexposure causes the verdigris formation in oxidized copper surfaces often observed on buildings. Artists both in its pure state and as colorants find aesthetic appeal in this valuable resource, along with medicinal properties serving as bacteriostatic agents, fungicides, and wood preservatives. Every living being counts on this mineral since it makes up part of cytochrome c oxidase. This metal accumulates in the respiratory enzymes found throughout life's systems from humans down to the simplest cellular structure of a protozoa. Found largely in bone, liver, and muscles, human beings store an amount equal to 1.4 - 2.1 milligrams for every kilogram it possesses, and does not undergo interaction with water, but under ambient air reacts with a brown layer protecting copper itself by oxidization (catalytic). Visible corrosion, or green verdigris from carbonate that appears in weathered structures including several public edifices of America and famous international landmarks. It changes to darker compounds under the sulfur elements to the surface upon tarnish of such metal over reaction with them within days when air meets chemical presence, forming an unbroken coat over all other oxidation. This has brought great profit due its mass amount obtained for commercial purpose in various open ground mine deposits which are located globally but primarily contain sites in Chile where this resource holds third portion while United States followed closely followed then both from their combined market with one of each containing percentage below and exceeding above respective ranges with that percentage also being found throughout entire world at lower ratio than that in South American locations alone. Its recovery in new technology for such a resource like leaching to produce extraction also brings additional copper source by application which will keep countries supplied worldwide if total availability is not yet enough today while future demands for higher output will meet global requests through mining activities that currently account half with no surplus. Since an adequate dietary supplement from our natural and man-made surroundings, one might expect low copper presence when its absence or excessive level leads towards deficiency, displaying physical health in human and mammals. Such instances have not reached conclusive scientific status while those for chronic cases, however can provide valuable knowledge since they display signs including severe body conditions like skin damage upon testing the subject via a blood count and further diagnostic of symptoms experienced and possible long-term development which might lead an unhealthy balance such as metabolic malfunction within that organ or more throughout body to extreme degrees affecting growth in both stature height or impaired organs, especially in liver where disease progresses over prolonged use if not managed effectively. Copper can also bring side effects when not handled properly during extraction; thus government safety regulation provides designated work guidelines for workplace usage including daily permissible exposure (1 mg/m^3 average within an eight-hour day), the National Institute for Occupational Safety and Health with REL recommended at 0.8 and its counterpart setting maximum amount as IDLH with an even lower value when immediate exposure could pose hazard at life-threatening amounts upon inhaling heavy air that brings risk towards workers and those indirectly involved such smoking through passive tobacco presence in surroundings and human lung function interaction of this mineral absorbed through various consumption processes leading potential unclear future damage
