Copper is widely used in electrical components due to its high electrical conductivity. It can be obtained either by extracting it from ores such as chalcopyrite (textCuFeS2\\text{CuFeS}_2textCuFeS2) or by recycling copper from obsolete consumer electronics.
State two distinct environmental advantages of obtaining copper by recycling electronics rather than extracting it from chalcopyrite ore.
