Iron Fertilization

Iron fertilization is a method used to enhance the growth of phytoplankton in the ocean by adding iron, a vital nutrient they need to thrive. Since phytoplankton consume carbon dioxide during photosynthesis, increasing their population can help reduce greenhouse gases in the atmosphere. This process can potentially combat climate change by encouraging a natural mechanism for carbon capture. However, it raises environmental concerns, as altering ocean ecosystems could have unintended consequences, and the long-term effectiveness of this approach is still being studied.
