Fracking. Is it a good thing or a bad thing?
This is a very hot topic where I come from and I thought it might be interesting to debate.
Here is how fracking works, in a nutshell (credit to the BBC for explaining the science behind it):
*Fracking is the process of drilling down into the earth before a high-pressure water mixture is directed at the rock to release the gas inside.
Water, sand and chemicals are injected into the rock at high pressure which allows the gas to flow out to the head of the well.
The process can be carried out vertically or, more commonly, by drilling horizontally to the rock layer and can create new pathways to release gas or can be used to extend existing channels.
The term fracking refers to how the rock is fractured apart by the high pressure mixture.*
Fracking can cause localised earth tremors and may cause contamination of groundwater supplies. However, supporters argue that it's better for a country to be self-sufficient with its energy needs, which would avoid the potential problems of buying fossil fuels from politically unstable countries in the Middle East.
