1 Mining Impacts on the environment

2 Mining effects on the Environment  Water Pollution  Air Pollution  Landscapes & Habitats  Underground Water Supplies  Waste Piles  Rising Surface Temperature

3 Water Pollution  Mining can have bad effects on surrounding surface and ground water if protective measures are not taken. The result can be unnaturally high concentrations of some chemicals, such as arsenic, sulfuric acid, and mercury over a significant area of surface or subsurface.[4] Runoff of mere soil or rock debris -although non-toxic- also devastates the surrounding vegetation.

4 Air Pollution  By destroying natural vegetation and mining deep into the ground, Mines bring toxic materials to the surface that can damage air quality. This is also accelerated by lack of vegetation.

5 Landscapes and Habitats  Mining destroys specific landscapes where they dig. This forces animals to move out of their natural habitiat and destroys ecosystems.  This is furthered when waste products and materials spread into the surrounding environments damaging or killing local animals and plants.

6 Underground Water Supplies  1.7% of the earths water is ground water, which is a lot when 96.6% of the earths water is in oceans  Groundwater is a major source of water for humans  Mining underground can impact groundwater through the release of chemicals and harmful chemicals into the ground which can soak into groundwater supplies

7 Waste Piles  are a significant environmental problem in many countries, including China, Russia, the US, Indonesia, Australia and South Africa. Underground coal fires can burn for centuries, filling the atmosphere with smoke laden with carbon-monoxide (CO), carbon- dioxide (CO2), methane (CH4), sulphur dioxide (SO2), nitrous oxides (NOx) and other greenhouse or toxic gases - as well as fly ash from vents and fissures.

8 Rising Surface Temperature  Over the past hundred years, the earths surface temperature has been seen to be rising as an effect of global warming.  Mining has been found to be a key influencer in raising the surface temperature of the earth.  The effects of this can cause Deforestation through drought, infertile soil, surface water evaporates quicker. Rising seas, change in ocean currents, increase in erosion. Changes in rain patterns and weather.
