The Global Sulfur Cycle And Emiliania Huxleyi

  • Dorion Sagan


Certain elements are planetary lifeblood. Like blood, they flow through the biosphere in limited supply. The carbon, sulfur, nitrogen, phosphorus, oxygen, and hydrogen that make up all organisms on Earth are not infinite. They must be continually redistributed, or cycled. Unlike an animal, the Earth has no heart pushing this global flow in a simple beat. Instead, the planet lives on a complex of different forces all pulsing to a syncopated rhythm. These forces include wind and ocean currents, the erosion and production of geological formations, and the motion of living organisms.
