Carbon Cycle CO 2 is very important for life on earth. Humans and animals inhale O 2 2 (carbon dioxide) during respiration, while plants absorb that CO 2 photosynthesis. This is how the carbon cycle maintains the CO 2 is released into the air by other means as well, which is absorbed by the oceans. Each day, the carbon content in the air is increasing due to human activities, such as the burning of fossil fuels and wood, by deforestation, by pollution, and so on. This is causing an increase in global temperatures and causing global climate change. (oxygen) and exhale CO and release O 2 during balance on earth. CO 2
