Under natural conditions, this cycle maintains a balance, with carbon absorbed and released through processes such as photosynthesis, respiration, and ocean exchange. Human activities have disrupted this balance by adding carbon to the atmosphere faster than natural systems can absorb it. Carbon dioxide is the most important greenhouse gas in …
