Lasting Soil: "Nature's Early Biochar"

Nature's Early Biochar
  300M years ago, on the shores of Pangean Sea, 
  the tide was unusually low, weather tumultuous. 
  Just before the storm, a lightning bolt came 
  out of the dark sky and zapped algae emerging 
  from the water on the rocky ledge.

  How do we know? Biochar with its typical internal 
  microscopic structure was produced by lightning 
  at that moment, and is still visible today.
