Ocean Fertilization

    • Ocean fertilization would add nutrients, often iron, to the ocean to prompt algal blooms, which would absorb more CO2 through photosynthesis.

  • However, by stimulating the growth of phytoplankton—the basis of the food chain—ocean fertilization could affect local and regional food productivity.
  • Vast algal blooms could also cause eutrophication and result in dead zones depleted of oxygen.
  • In addition to its possible ecosystem impacts, it also has less potential to sequester carbon over the long term
