Engineered nanoparticles can help phytoplankton kidnap the excess CO2 on Earth

The solution to our carbon problem is floating in the oceans.

Phytoplankton are microscopic organisms (can be bacteria, algae, or plants) that perform photosynthesis in oceans and eliminate excess carbon dioxide from Earth’s atmosphere. They sequester about 40 percent of the total carbon produced every year globally and, therefore, also play a major role in mitigating global warming.

A team of researchers from the Pacific Northwest National Laboratory (PNNL) has proposed that by feeding engineered nanoparticles (ENPs) as fertilizers to phytoplankton. Humans can increase the growth of these microorganisms in oceans and eventually fix more CO2 from Earth than ever.
