Extractive industries like mining for any ore element oil or gem are not our most earth-friendly activity. Refining takes a lot of energy as well. It’s hard to live in our modern world without extraction so we have to work harder to use our resources eﬃciently and make conscientious decisions about how we apply those resources.
The miners mined for zinc copper lead nickel iron cobalt gold antimony and tin. These minerals are found in the metal mining sector and when the excess dirt has been dug up the miners don't care and throw the dirt into the waters polluting the waters.

Different types of mining have various impacts on land. For example strip mining results in the clearing of trees plants and topsoil 2 . One effect of this type of mining on the environment is the pervasive problem of soil erosion which in turn leads to the pollution of waterways.
The Australian Bureau of Statistics ABS states that in the year to March 2011 the value of mining exports was $155 billion and represented 52.8% of the value of total exports from this country with the bulk of that being contributed by iron ore and coal.
Iron ore is the world’s third most produced commodity by volume - after crude oil and coal - and the second most traded commodity - 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.
