# Zooplankton could impact ocean-based CO2 removal strategies

As the world seeks to reduce emissions and remove CO2 from the atmosphere, ocean-based approaches are gaining attention due to their potential lower cost compared to direct air capture. However, the marine carbon cycle is complex, and scientists must understand the intricate natural processes that could affect the efficiency and safety of these techniques. Recent research highlights the importance of zooplankton appetites, which can significantly influence the strength of the biological carbon pump. By altering phytoplankton communities, CO2 removal technologies could inadvertently change zooplankton populations and their grazing, compromising or enhancing carbon storage. Overcoming the challenges of observing and modelling zooplankton dynamics is crucial for establishing reliable standards and paving the way for a responsible CO₂ removal industry.
