Historically, gold usage can be found back towards 3 000 B.C. in ancient Egypt in the making of statues, temples, coins, and even face masks of deceased pharaohs, like that of the famous King Tut. Today, it is used in electronics such as computers, as a wire that connects circuits to semi-conductors. In telephones, gold may be found inside the cover of the mouthpiece as a miniature transmitter, the diaphragm, which contains a gold plated dome. Even televisions and V.C.R.�s use gold wires that process broadcast signals into a picture.
Within industry, gold is used in the making of airbags for automobiles. A sensor near the bumper of the car is gold-plated and sensor send a signal when activated for the airbag to deploy. On an airplane gold is frequently found in the engine, and even in a coating on the windows to prevent fogging. Thus, we are very fortunate that gold is a part of our lives.
There are few, if any negative effects upon the environment concerning the mining of gold because gold mining companies must make very large environmental impact studies so that help protect local wildlife before a mining permit can be given. Thus, the mining of gold in North America is usually forced (especially in the United States) to operate responsibly towards the environment to protect such wildlife as native fish and endangered species. However in the United States the gold mining industry is subjected to a large variety of state and federal laws to cover almost every different aspect of gold mining operations.
