During tonight’s national coverage fracking was a topic brought up on multiple occasions. Can someone explain what it is and the pros and cons of it? Need it because a google search did not help :/
In: Biology
Fracking refers to the method of pumping millions of gallons of water into oil shale formations underground. Oil shale cannot be mined for oil in the traditional way.
By hydraulically fracturing the oil shale, the oil and natural gas trapped within gets freed and the oil can be easily extracted while the natural gas just escapes into the environment, doing fun things like contaminating the ground water and spoiling the water table.
