Zooplankton, often overlooked, migrate and store vast amounts of carbon, equating their efforts to the emissions from millions of cars.

Tiny Zooplankton: Heroes in the Fight Against Climate Change
New research reveals how these small marine creatures play a significant role in sequestering carbon to combat global warming.
Scientists have recently uncovered the crucial role that tiny zooplankton play in battling climate change through a remarkable annual migration in the Southern Ocean. This little-known group of marine animals, commonly used as fish food, has been found to significantly contribute to carbon sequestration, essentially locking away carbon emissions that would otherwise exacerbate global warming. The research reveals that these small but mighty creatures, during their seasonal journeys, absorb and store enough carbon to offset the annual emissions of approximately 55 million petrol cars.
Lead researcher Dr. Guang Yang from the Chinese Academy of Sciences highlights the surprising extent of these animals' contributions to carbon storage. According to the researchers, zooplankton gorge on phytoplankton during spring, accumulating fat in preparation for their migration into the deep ocean, where they gradually burn this fat, effectively sequestering carbon. This process has far-reaching implications for climate models and highlights the importance of understanding these microscopic players in the broader context of climate change.
Despite their essential role, zooplankton remain relatively unappreciated compared to larger Antarctic animals like whales and penguins. The research also underscores growing threats to these creatures, including rising ocean temperatures and commercial krill harvesting, which could potentially disrupt their life cycles and decrease their populations.
The study compiled data dating back to the 1920s and illustrates how climate change impacts these organisms, as well as their vital role in maintaining Earth’s climate balance. Scientists are now pushing for enhanced incorporation of these findings into climate predictive models, emphasizing that without zooplankton, levels of atmospheric CO2 could be nearly double what they are today. This new revelation serves as a reminder of the interconnectedness of marine ecosystems in the fight against climate change and the urgent need for their protection.
