What is Mining?

Mining is the extraction of valuable minerals or geological materials from the earth, which forms the mineralized package of economic interest to the miner. Basically, mining is the foundation of industrial civilization. It is the process of extracting minerals like gold, silver, copper, nickel and uranium (metallic) and salt, potash, coal and oil (nonmetallic) formations that concentrate naturally in the earth. In fact, other than agriculture product, raw materials also come from mining.

How it can affect the environment?

Mining can give negative effect to environment such as deforestation, water pollution and also land and river dredging. As usual, before they start mining activity they have to clear the site. This mean, they have to cut the trees. It leads to deforestation. 

Deforestation reduces habitable areas for wildlife animals.

Chemicals are used to amalgamate extractions. Unfortunately, these chemicals include the likes of mercury and cyanide, which have harmful effects on human health when accidentally consumed. It happen when they accidentally pass through pipes from the mines is discharged into surrounding natural bodies of water.  

Water pollution 

Land dredging occurs when large holes are dug out and filled with contaminated water from mine tailing. They become a breeding nest for mosquitoes and other disease-carrying insects, which could then lead to the spread of diseases like dengue fever.

 Improper disposal of these elements lead to water pollution as well
