OXYGEN: The main source of atmospheric free oxygen is photosynthesis, which produces sugars and free oxygen from carbon dioxide and water: Photosynthesizing organisms include the plant life of the land areas as well as the phytoplankton of the oceans.

CARBON DIOXIDE: There are both natural and human sources of carbon dioxide emissions. Natural sources include decomposition, ocean release and respiration. Human sources come from activities like cement production, deforestation as well as the burning of fossil fuels like coal, oil and natural gas.
