Detailed explanation-1: -Deforestation and the carbon cycle This is converted into carbon and stored in the plant’s branches, leaves, trunks, roots and in the soil. When forests are cleared or burnt, stored carbon is released into the atmosphere, mainly as carbon dioxide.

Detailed explanation-2: -Burning fossil fuels and cutting down forests is resulting in worsening climate change. This is occurring as CO₂ is being added to the atmosphere by these activities faster than carbon reservoirs can reabsorb it. Deforestation, therefore, has a clear and substantial negative impact on the carbon cycle.

Detailed explanation-3: -Human activities have a tremendous impact on the carbon cycle. Burning fossil fuels, changing land use, and using limestone to make concrete all transfer significant quantities of carbon into the atmosphere.
