· Miners cannot control "slash and burn" agriculture, but political leaders can. As such, the NYDF report authors suggest approaching environmental issues from a broader perspective. In remote forested areas, mining can lead to game hunting and monocultural farming. Along with deforestation, this in turn leads to poor biodiversity.

· By Aly Azhar. A new report titled Red Water documents the social, environmental, economic, and health impacts of gold mining in Porgera, Papua New Guinea. The report finds that the communities affected by mining do not have access to consistent and safe drinking water. This is due, in part, to the fact that the PNG government has not met its human rights obligations to .
Two producers provided information on the fluoride emission to water (as total particles in suspension or unspecified). The calculated emission factors are and 233 g/t. Based on a total production in the EU of 335,546 tonnes, the resulting emission of fluoride from CaF2production to the aquatic environment will range from to 78t.

Fluorine in the environment. Annual world production of the mineral fluorite in around 4 million tonnes, and there are around 120 million tonnes of mineral reserves. The main mining areas for fluorite are China, Mexico and Western Europe. Fluorine occurs naturally in the earth's crust where it can be found in rocks, coal and clay.
· Potential Environmental Problems A. Mining operation itself – Disposal of a large amount of rock and waste – Noise – Dust Beneficiation Smelting and refining. 37. From Underground Mining Subsidence – Block/caving – Room and pillar – Salt mining .
Public health problems. Environmental degradation can also lead to severe public health issues. In many countries, due to deforestation, mining or other practices caused by human interactions with nature, the probability of floods or other natural disasters will increase over time. The effects of those natural disasters will be horrible.
