Fracking, or Hydraulic Fracturing, is a method of extracting hard-to-get oil and gas from shale. For the most part, fossil fuels originally formed in shale, which was in turn laid down by near surface life in anoxic seas. Sunlight powered a high turnover of near surface plankton, algae, and bacteria, but oxygen-poor co... | |
