The role of the carbon cycle in environmental science is crucial for regulating Earth’s climate and sustaining life. It describes the movement of carbon among the atmosphere, oceans, soil, plants, and animals. Through processes like photosynthesis, respiration, decomposition, and combustion, carbon is continually transformed and recycled. This cycle helps maintain a balance of carbon dioxide in the atmosphere, influencing global temperatures and climate patterns. Disruptions in the carbon cycle, due to human activities like fossil fuel combustion and deforestation, can lead to increased greenhouse gas concentrations, contributing to climate change and global warming.
