Carbon sinks are natural or artificial reservoirs that absorb and store carbon dioxide from the atmosphere. They play a crucial role in reducing the amount of carbon dioxide in the atmosphere and mitigating the effects of climate change. Natural carbon sinks include forests, oceans, and soil, which absorb carbon through photosynthesis, oceanic processes, and decomposition of organic matter. Artificial carbon sinks, such as carbon capture and storage technologies, are also being developed to help reduce greenhouse gas emissions. Research in this area focuses on understanding the processes of carbon uptake, storage, and release in different ecosystems, as well as improving carbon sink enhancement and management strategies. Ultimately, the goal is to enhance the capacity of carbon sinks to effectively sequester carbon and help combat climate change.
