Global Carbon Cycle:Its Impact On Terrestrial Ecosystem, Environmental Cahange, Composition Of Atmosphere And Sustainability

Abstract

Atmospheric greenhouse gases mainly carbon dioxide is responsible for the equilibrium between natural biological and geochemical processes in the atmosphere. this balance is being changed due to anthropogenic-related increase in the atmospheric concentration of these gases, mostly from burning of fossil fuel and modifications in land use/land cover (LULC). This is consequently causing the prevailing climate change being experienced by the global community. The current paper is aimed at reviewing existing literature relatively to terrestrial carbon stocks through time. Here, it has been demonstrated that climate change is a global problem to which responses have been focused on reducing greenhouse gases’ release into the atmosphere, as well as the observation of carbon taken up by the terrestrial ecosystem. In addition, the long-term net flux of carbon from the biosphere to the atmosphere is somewhat dependent on the alterations in land use/land cover, as well as the modifications in forest biomass due to forest management and regrowth. Terrestrial Carbons sinks may be responsible for taking up about 1/3 of all the carbon dioxide that is released into the atmosphere.
