"Ocean fertilization" refers to the act of adding nutrients to the ocean to stimulate the growth of marine plants, like algae. This process is done to promote the absorption of carbon dioxide from the atmosphere, as these plants need CO2 for photosynthesis. The increased growth of these plants can potentially help combat climate change by reducing the amount of CO2 in the atmosphere. However, it is still a subject of debate and research due to potential ecological and environmental impacts.
