Mining
Mining for coal is something that is widely known, but did you know that diamonds, uranium, copper, and other non-renewable natural resources are also mined? There are two types of mining; surface and subsurface. Questions about the methods and types of mining, what ores are mined, and related questions should be asked in this category.

It may not be evil, but it is necessary for life beyond the stage of being a caveman. Come to think of it, even the caveman mined rocks to make stone spearheads.

It is powered by electricity carried on copper wires (mining) from the powerplant, which probably uses coal or uranium (mining) The food you ate tonight was transported in a metal truck (mining) that traveled on a paved road that was made with crushed stone (mining).

Hydraulic mining, or hydraulicking, is a form of mining that uses high-pressure jets of water to dislodge rock material or move sediment. In the placer mining of gold or tin, the resulting water-sediment slurry is directed through sluice boxes to remove the gold.
What is the method of hydraulic mining?
Spraying high pressure water jets against mountain sides to wash away the mountain and allow valuable metals like gold and platinum to be captured in enormous sluice boxes. The muddy runoff from hydraulic operations kill most fish and other river life and causes silting over of farmland in flat lands that the drainage rivers run through. It is now banned in most places.
What are some of the controversy of mining today?
Mining is one of the main sources of energy for the planet today. We must mine for coal, oil, and natural gas, as they are not available anywhere else than under the ground. Mining also must be used to obtain raw metals such as iron, gold and tin, and raw materials used in fusion, such as uranium.
ADVANTAGES:
- Mining allows us to obtain materials and fuels that otherwise would not be available to us.
- Mining creates jobs for people
- Mining is essential to most economies
- Mining today can be done reasonably cleanly
- Closed mines don't damage the aesthetic environment.
- Mining nowadays is quite efficient and alot less dangerous.
DISADVANTAGES:
- Mining is very polluting to the environment. Large machines are used to drill the wanted product out of the rock/ground.
- Mining is not sustainable, especially with fuel mining. Fuels such as oil are being mined at a much faster rate than is naturally being produced.
- Mining creates conflict between countries and govenrments. Desert countries such as Iran hold the most amounts of oil, which can often lead to larger countries battling each other to claim it.
- Open mines are not aesthetically pleasing. In places such as the Amazon rainforest, they destroy natural habitats.
- If not correctly done, mining can cause very large amouns of waste, and if not dealt with efficiently (many illegal mining companies do this) end up destroying areas and polluting habitats such as seas and freshwater rivers.
- Spillages are often very damaging to the environment. Take the BP oil spill!
