yes and no. Like all chemicals too much of it would be harmful to the environment however studies have shown that adding iron to the seas cause the algae to bloom then die and sink to the bottom taking carbon dioxide with it. Therefore burying the carbon dioxide for centuries. This could help reduce the impact of climate change. However some critics are weary and are warning of unwanted environmental side effects.
