Krill are some of the smallest living creatures in the ocean. Resembling shrimp, these tiny crustaceans have a significant impact on our environment. Each year, a single krill stores up to 12 bn tonnes of carbon for up to seven years (their average lifespan) by consuming surface phytoplankton, a small plant-like organism which absorbs C02 from the atmosphere through photosynthesis. Feeding on these algae and bacteria, they produce dense, carbon-rich fecal pellets that sink to the bottom of the ocean. Therefore, the carbon instead of returning back into the atmosphere, gets stored in the…
