Step-by-step explanation:
Human activities have a significant impact on the carbon cycle, particularly in terms of the amount of carbon dioxide (CO2) that is released into the atmosphere. The combustion of fossil fuels, such as oil, gas, and coal, releases vast amounts of CO2 into the atmosphere, contributing to climate change.
Deforestation is another human activity that influences the carbon cycle. Trees absorb CO2 from the atmosphere through photosynthesis and store it as carbon. When trees are cut down and burned or left to decay, this stored carbon is released back into the atmosphere.
Agricultural practices, such as plowing and livestock farming, also impact the carbon cycle. Plowing releases CO2 from the soil, and livestock farming produces methane (CH4), a potent greenhouse gas.
Additionally, industrial processes and the construction of buildings and infrastructure also contribute to CO2 emissions. Overall, human activities have substantially altered the carbon cycle, leading to significant environmental consequences.
