Transcript of MINING
“I don’t understand why when we destroy something created by man we call it
, but when we destroy something by nature we call it
― Ed Begley Jr.
Loss of Biodiversity
Effects of Water Pollution
The human ingestion of unclean water as organic pollution can lead to sickness or death
Water can be ingested by animals too! Which can cause the loss of biodiversity
The spreading of disease and bacteria in the ocean
The decrease of oxygen in the water can suffocate sea creatures
And many more!
All of which can affect the health of our earth!
The Loretto Abbey Peace and Development Club, based off of the Canadian Catholic Organization for Development and Peace, is focusing efforts this year on bringing awareness on the many consequences of irresponsible mining. Mine-affected communities in Africa, Asia and Latin America are experiencing conflict, pollution, forced displacements and other negative impacts from the presence of Canadian mines.

Water Pollution in El Salvador
A Canadian mining company called the Pacific Rim Mining Corporation is suing El Salvador for refusing them to mine gold without a legitimate environmental regulation in place. The disposal of cyanide and mercury (which are used for the mining of gold) in the Lempa River will intoxicate the river's water, which is the source of water for four million inhabitants. Soon enough, it will be difficult for the residents to find fresh clean water to use, or else they'll die from the polluted water.
How to Minimize Water Pollution
By monitoring the waste deposited into the water by mining companies
Force governments to implement more water-treating plants
Monitor or decrease our daily usage of water, especially in our homes
Have more countries enforce environmental regulations to avoid further pollution of their water sources
How Does Mining Cause Water Pollution?
By the release of harmful chemicals such as cyanide and mercury into the water
Also, by using chemicals used for mining combined with machinery, deforestations, excavations, and violation of virgin lands and rainforests causes a great impact in nature as a whole
"Erosion is one of those problems that nickels and dimes you to death: One rainstorm can wash away 1 mm (.04 inches) of dirt. It doesn't sound like much, but when you consider a hectare (2.5 acres), it would take 13 tons of topsoil -- or 20 years if left to natural processes -- to replace that loss," Pimentel said. "And that kind of loss occurs year after year by wind and rain around the world."
Canada is considered one of the world's leading mining country as mining companies exploit minerals in other countries. The geographical map shows that Canada, unlike many other countries, has stable soil.
Definition: the process of eroding soil by either wind or rain.
In this case, it's erosion due to mining.
Case Study: The United States
The United States experiences much soil erosion not only due to natural causes such as rain and water but also due to mining. The United States is losing soil 10 times faster than the natural replenishment rate. The economic impact of soil erosion costs the nation about $37.6 billion each year in productivity losses and damage from soil erosion is estimated at $400 billion per year. Soil erosion affects farmers' and their crops as the arability of their land is affected by soil erosion. The chemicals used during mining destroys the natural nutrients in soil and most times, the environment is unable to be restored.
"If you can't grow it, you have to mine it."
“Our products and services are essential to sustaining quality of life, the copper that we produce certainly drives the Internet, energy lights our homes and so on."
Lindsay is the CEO of Teck Resources, Canada's largest diversified resource company. It is associated with Columbia River case in which it was continuously contaminating the river, using it as a free waste disposal.
Robert is a well-known mining tycoon with a net worth of $1.5 billion. He develops his mines in South Africa and the Democratic Republic of the Congo. Many of the laws in Canada are not international and so oftentimes, mining companies do not follow the strict laws placed in Canada. Instead, they follow the laws of the country they are exploiting as they are not as strict. In turn, the workers and environment may be negatively affected.
How Mining Affects Soil
-Cover plants are removed while preparing the mining site. As a result, surface runoff increases and soil nutrients and soil organic matter decreases
-The soil is unable to restore itself as the layers of soil that each offer a purpose, have been removed
-Soil is unable to handle the high pH levels from the chemicals used
For The Plants and The Animals
With the eroding soil, deforestation and water pollution, comes one of the BIGGEST environmental losses due to mining: Biodiversity.
With a topic like this, you need to see it to believe it
Case Study : The Amazon Rainforest
El Dorado may be the stuff of myth and legends, but gold fever is leaving clear marks all over the region
Amazon is rich in mineral assets like copper, tin, nickel, bauxite, manganese, iron ore and gold
In the Carajas Mineral Province, Brazil, maybe the world’s largest copper reserve (iron ore, manganese and gold are already found there), wood from surrounding forest is cut for charcoal to fuel pig iron plants, resulting in annual deforestation of 6,100 km
Displacement of People
In 1995, in Guyana, the mining industry tailed four billion liters of waste water into peoples main source of water
People were forced to move out of villages in search of clean water, abandoning their livelihoods and farms.
SOLUTIONS - WHAT CAN YOU DO?
BEFORE & AFTER
Use recycled materials instead of mined materials
Cleaning up mining pollution is costly, this is one of the many reasons why mining industries abandon mining sites.
to environmental performance institutes that clean up after abandoned mines. These organizations restore the environment as it once was
Have your class
adopt an animal
! One of the most mining-effected species is the Tarsier. Those little guys really need your help!
