Environment and Health
Our bodies depend on copper for neurological activity, for creating our own internal heat, and for communication between and among cells. Copper is helps certain foods make hemoglobin in our blood. The presence of copper is also necessary for the function of critical enzymes in our metabolism. A deficiency in copper is one factor leading to an increased risk of high cholesterol and coronary heart disease. Environmentally, copper is one of the friendliest metals around. Copper never goes bad - it can be recycled over and over again. It actually has the highest recycling rate of any engineering metal in the world. Copper also functions as a defense against germs - because it is naturally biostatic, bacteria growth is inhibited on its surface. Many hospitals install copper or copper-alloy doorknobs, push panels and other hardware to protect against the transfer of disease.
Copper is an essential material - and not only when it comes to electrical wiring, plumbing or architecture. It is a key ingredient in our health and it helps to maintain a sound, safe environment.
