Combustion engines, as in cars, trains, ships and airplanes, the automotive industry began in 1890, but in reality since 1950 it can already be felt which began producing carbon monoxide, nitrous oxide and oxide gas pollution. These three toxic gases could easily affect the ozone layer, and today we can see the results including rising earth temperatures, melting glaciers in the north and south poles, and rising sea levels. Mining operations, this industry is really related to the improvement of our life because we can extract some necessary metals such as iron, copper and aluminum. But on the other hand, we can see that this useful industry is harming the environment by releasing carbon monoxide, sulfur dioxide and nitrous oxide into the environment.
