Since the beginning of civilization, human beings have used different materials such as stones or metals obtained from the surface of the Earth to satisfy their different needs. Although this does not have much to do with current modern mining, we could consider this fact as its oldest origins, in the sense that human beings have always exploited the environment in which they live for their survival or improvement of life.
But, how mineral extraction affects the environment? In this Green Ecologist article, we ask you this question and give you the answer, mainly commenting on the negative consequences of this activity, among other aspects.
Over time, mining evolved from the oldest known, dated approximately 43,000 years ago (Lion Caves in Swaziland), through mining in ancient Egypt, Greece or Rome. However, modern mining with its large exploitations emerged during the last three centuries (19th, 20th and 21st centuries) when the population and industrial growth of the planet increased exponentially and, with it, the needs of the population.
These needs include a greater demand for raw materials for construction, industry or energy, which in many cases are obtained from onshore deposits. However, the increasingly uncontrolled exploitation of our natural resources carries with it a series of problems. A) Yes, modern mining also has negative consequences for our planet.
Some negative consequences of modern mining for the environment, which turn out to be the most important, are the following:
The negative impacts of mineral extraction on the environment, they also depend to a large extent on the type of mining, fundamentally distinguishing two types of mines: underground mines and open pit mines.
They are excavated as interconnected galleries under the ground, using explosives. In general, the environmental impact of this type of mines is less, since the changes in the land surface are minor, although water and aquifer contamination also occurs. These types of mines are progressively being replaced by more efficient methods.
They currently represent the vast majority of mining operations. Its environmental impact is much greater than the previous ones, since it influences the environment more, causing deforestation, greater loss of habitats or water pollution. They differ in open-pit mines themselves, quarries (dangerous due to their greater proximity to urban areas and give rise to urban landfills) and leaching mining, which uses chemical products to wash (leach) the minerals to be extracted, causing great pollution to the waters.
This is an example that we can find in Spain. An interesting area has been the Leonese town of Laciana. It represents an area of valleys with a great richness in biodiversity, with declared areas of community interest (SCI), special protection for birds (ZEPA) or UNESCO Biosphere Reserves. In this valley, they have proliferated, in recent years, large number of mining operations, many of them undeclared, currently leaving a land totally depleted, that is, totally exhausted by having it over-exploited, and contaminated.
