Abstract
The discussion about greenhouse gases emission mitigation focuses on the reduction of fossil fuels usage, which is extremely costly from the economic and social viewpoint. The analyses of CO2 and CH4 fluxes in the environment showed that intensifying natural photosynthesis and respiration process may significantly contribute to the mitigation of greenhouse gases emission. It has been proven that the intensity of photosynthesis in land ecosystems could compensate for the increase of CO2 emission from anthropological sources.
