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
