The carbon cycle is the movement of carbon from cellular respiration and human interference to the atmosphere. Human interference adds an excessive amount of carbon to the atmosphere, resulting in an imbalance. This imbalance means there is less oxygen available to organisms who need it, such as humans and animals. Burning of fossil fuels and deforestation are some contributors into the imbalance of carbon and oxygen in the atmosphere. Hope this helps! :)
