Diamond Mines: Spreading Pollution And Devastation

Diamond mining has a range of negative impacts on the environment, local ecosystems, and communities. Diamond mines exist in a variety of ecosystems, from the African Savannah to the Arctic, and the process of diamond mining can lead to massive loss of habitat and vegetation, soil erosion, deforestation, and ecosystem destruction. Diamond mining also impacts local communities, with poor working conditions, low wages, and the use of child labor in some countries. The pollution caused by diamond mining can take many forms, from water pollution to the release of harmful chemicals and the creation of ground-level ozone.

Water pollution

Diamond mining has a significant impact on water sources, causing pollution and environmental degradation. One of the main ways diamond mine pollution spreads through water is through the destruction of fish habitats and water sources. This is done through the draining of lakes and the destruction of streams, which results in the loss of fish habitats and irreversible changes to water quality. In some cases, diamond mining companies inject large amounts of ammonia under lake beds to extract minerals, which directly harms fish populations and contaminates nearby lakes. These toxic chemicals can also be carried by wind, spreading pollution to other water sources and communities.

The process of diamond mining can also lead to soil erosion, which has a direct impact on water sources. Erosion results from the removal of vegetation and topsoil, leaving the land vulnerable to wind and water damage. This soil deterioration and surface runoff can contaminate nearby waterways, reducing water quality and impacting the ecosystems that rely on them. In addition, the creation of diamond mines can involve building dams, which can change the course of rivers and destabilize ecosystems.

The closure of diamond mines can also result in water pollution. When a mine is exhausted, there is often a lack of regulation and infrastructure to restore the ecosystem. The inadequate replacement of extracted material can lead to water pollution, making the land susceptible to erosion and flooding. These abandoned mines can become breeding grounds for waterborne viruses, parasites, and mosquitoes, posing health risks to nearby communities.

The impact of diamond mine pollution on water sources extends beyond the immediate vicinity of the mines. In some cases, water quality changes have been measured up to 200 km downstream from the mining sites. The pollution and destruction of water sources have severe consequences for the environment, displacing wildlife and threatening the livelihoods of people who depend on these water sources for farming and survival.

Overall, diamond mine pollution spread through water sources in several ways, including the direct contamination of water sources, soil erosion, and the disruption of natural water flows. The lack of regulation and restoration efforts exacerbates the problem, leading to long-lasting environmental and social impacts.

Soil erosion

Diamond mining operations scrape away millions of cubic yards of soil and plant life daily, leading to substantial soil erosion. The removal of vegetation and topsoil leaves the land vulnerable to wind and water damage, causing further deterioration. This erosion can alter the course of waterways, affecting both land and water environments. The sediment and erosion moving from the original Kimberlite Pipes result in the accumulation of diamonds in rivers and lake beds over millennia.

Additionally, the large walls built to divert the natural flow of water during mining operations further contribute to soil erosion by altering water flow patterns and exacerbating the vulnerability of the surrounding areas to water damage.

The environmental impact of diamond mining extends beyond soil erosion, including deforestation, ecosystem destruction, and water pollution. The demand for diamonds continues to rise, and the expansion of mining operations into previously untouched areas exacerbates these issues.

Deforestation

Diamond mining has been associated with land clearance, deforestation, habitat destruction, and human rights abuses. The energy consumption and carbon emissions related to diamond mining are significant, and the industry has a history of ethical challenges.

For every carat of diamond mined using traditional methods, nearly 100 square feet of land is disturbed, and over 5798 pounds of mineral waste is created. Diamond mining companies often clear large areas of land to facilitate access to diamond-rich areas. This involves removing trees and vegetation, leading to the degradation of ecosystems and forests.

In countries like the Democratic Republic of Congo (DRC), Ghana, and Sierra Leone, alluvial and small-scale mining (ASM) is the prevailing diamond extraction technique. This process consumes land as sediments are dug up and tailings are deposited. ASM has led to several socio-environmental impacts in the DRC, including deforestation, river pollution, water resources exploitation, and dangerous work environments.

The heavy machinery and equipment used in diamond mining can also release pollutants into the surrounding ecosystems. Water is used for washing and processing extracted ore, which can result in water pollution. The use of diesel in generators and vehicles contributes to air pollution and greenhouse gas emissions.

The impact of diamond mining on deforestation and habitat destruction has led to species displacement and the endangerment of animal species. Nature reserves are being created to protect species that can no longer migrate through mined areas.

Ozone layer depletion

Diamond mining has been linked to ozone layer depletion, particularly in the Arctic. The machinery used in open-pit mines runs on chemicals that can destroy or weaken the upper ozone layer, leading to an increase in ground-level ozone. This ground-level ozone has the potential to spread across Canada, affecting communities far from the source due to wind.

Ozone depletion refers to a lowered total amount of ozone in the Earth's upper atmosphere and a larger decrease in stratospheric ozone around the Earth's polar regions, known as the ozone hole. The ozone hole is a phenomenon observed since the late 1970s, with the Antarctic ozone hole being one of the largest on record in September 2023. The ozone layer depletion is caused by ozone-depleting substances (ODS), which include manufactured halocarbons like chlorofluorocarbons (CFCs) and other chemicals used as refrigerants, solvents, propellants, and foam-blowing agents. These substances are transported into the stratosphere, where they release atoms that destroy ozone molecules.

The depletion of the upper-level ozone layer has significant impacts. It allows more UV-B radiation to reach the Earth's surface, causing harm to plant life and terrestrial plant productivity. This radiation can also damage crops, trees, and vegetation growth. The increased UV-B radiation can lead to a decrease in plant growth and an increase in oxidative stress, as plants produce harmful volatile organic compounds like isoprenes when exposed to high levels of UV radiation. These emissions from plants contribute to air pollution and increase the amount of carbon in the atmosphere, ultimately impacting climate change.

The effects of ozone depletion are particularly pronounced in the Arctic, where it can cause faster melting of snow due to increased UV radiation. The habitats and food supplies of many endangered species are being destroyed, and isolated Aboriginal groups are facing food shortages as a result. The risk of ground-level ozone thickening in the Arctic has led to a push for the adoption of man-made or lab-grown diamonds, which do not require the same harmful pollutants as natural diamond mining.

Spread of disease

Diamond mining has been associated with a range of negative impacts, including the spread of diseases. The working conditions in most diamond-mining countries are terrible, with Africa, in particular, known for its poor working conditions and extremely low wages, sometimes as little as \$1 per day. Children are also often forced into labour in Africa, facing physical and sexual abuse while being forced to produce diamonds.

The poor working conditions and sanitation in diamond mines contribute to the spread of diseases among labourers. The close quarters and inadequate sanitation facilities facilitate the transmission of illnesses, which can quickly spread in such environments. This is further exacerbated by the hazardous and abusive conditions that children labourers are subjected to.

The creation of stagnant water in open pits at diamond mines has been identified as a cause of diseases not only among workers but also among nearby residents. Stagnant water serves as a breeding ground for mosquitoes, which can spread life-threatening diseases such as malaria and dengue fever. This issue is observed in South Africa and Sierra Leone, where stagnant water at disused mines has attracted mosquitoes, leading to malaria cases.

Additionally, the use of heavy machinery and equipment in diamond mining can release pollutants into surrounding ecosystems. This includes the release of chemicals that can destroy or weaken the upper ozone layer, causing an increase in carcinogenic radiation and crop damage. The machinery used in open-pit mines, fuelled by millions of litres of diesel, contributes to higher levels of CO2 and greenhouse gases, leading to global warming.

The negative impacts of diamond mining on human health and the environment highlight the importance of responsible and sustainable mining practices. While the demand for diamonds continues to rise, it is crucial to address these issues and explore alternative methods, such as lab-grown diamonds, to reduce the harmful effects of traditional mining practices.
