Carbon dioxide can be removed from the atmosphere by increasing the phytoplankton population in the oceans using nutrients. Life cycle assessment, cost analyses and data from previous studies reveal that engineered nanoparticles could increase the efficiency of this process and that it can be made affordable, viable, and safe for marine ecosystems.
