Explanation:
<em>I believe the effects are the main ingredient in the production of steel is iron ore mined from Earth. Over 2,000 million tons of iron ore is mined each year, about 95 percent is used by the steel industry. Iron ore is the world’s third most produced commodity by volume after crude oil and coal and the second most traded commodity but only beaten by crude oil. The mining of iron ore is highly energy intensive and causes air pollution in the form of nitrous oxide, carbon dioxide, carbon monoxide, and sulfur dioxide from diesel generators, trucks and other equipment. Also the mining of iron ore also causes water pollution of heavy metals and acid that drains from the mines. Acid drainage can go on for thousands of years after the mining activities have stopped.</em>
