In the search for oil and gas, we have drilled deep beneath the oceans surface and the ground, to tap into the energy wells trapped there. Today, we need more energy than ever before in our history, but the oil and gas fields may soon dry up. One option being considered is fracking. Rock is fractured underground in order to reach deposits. Discover how people use fracking to harness the before-unreachable supplies of gas and oil beneath Earths surface, the challenges of this form of mining, and the controversies surrounding it.
