The 'Breathing Earth'. Map showing the global distribution of release and absorption of carbon dioxide by the Earth's biosphere for a typical June. The map is a result of a complex computer model of biological processes across the world. The colours represent the flow of carbon dioxide in units of grammes per square metre per month from red (120 g/sq.m released) through yellow (no net flow) to green (100 g/sq.m absorbed). Note the high activity of plants in the Northern Hemisphere fixing the gas from the air (green), and the large areas of gas release resulting from microbial plant decomposition in the Southern Hemisphere and south Asia (orange and red).
