Would dumping iron into the oceans to help sequester carbon result in an overgrowth of algae?

    Theoretically yes. This has been suggested as a carbon sequestration technique, but the adverse effects of raising the ocean’s iron and carbon content are not well known. The overgrowth of algae would result in much carbon being taken out of the atmosphere as the algae converts it to oxygen through photosynthesis. Another potential problem is that lack of sunlight would be had and could cause potentially devastating effects on marine life around the algae bloom.
