Exploring the secrets of carbon dioxide sequestation by phytoplankton

The discussion over the best ways to reduce greenhouse gas emissions and remove existing carbon dioxide from the atmosphere often includes measures that entail planting trees. But this discussion overlooks an important factor: trees are not the only plants that take up carbon dioxide. In fact, microscopic marine phytoplankton already play a critical role in regulating today's carbon cycles.
