100 kg/ 1 million dollars of exploitation and destruction

So what is the true cost of this 100 kg gold coin? Well I decided to find out. Gold mining exploits the environment on countless levels. The impact of gold mining begins with threatening biodiversity from the onslaught of pushing roads into remote and often pristine wilderness. Land is cleared for operations and the mechanized mining process is highly devastating to landscape and surrounding watersheds. After the mine has ceased production the contamination lingers. Mercury and cyanide poison the environment of gold mines and the adjacent ecosystems causing harsh, everlasting damage. This can result in the permanent destruction of many goods and services that ecosystems provide. The toll gold mining extracts from the surrounding human population is also steep; miners suffer from exposure to toxic levels of chemicals and the inhabitants deal with polluted water and soils. The legacy of gold mining demands a high price economically and environmentally.
