Copper production & environmental impact

• Copper tools started to emerge as early as 3500 BC in Israel. Its property of alloying with other metals (particularly tin) was discovered about 500 years later and heralded the Bronze Age, which started in southern Europe between 3000 and 2500 BC. • Copper has been found used in buildings from an early age.
