The ways humans alter the biogeochemical cycles, and some of their environmental outcomes. Introduction: Biogeochemical cycles include the fluctuations of chemical substances between the varied parts of the Earth, that is, from living to non-living, from soils to plants, and from atmosphere to land and then to sea. They are known as cycles as the matter is always conserved. However, human activities have mobilized elements of the Earth and have upsurged their cycles. For example, more than double the concentration of nitrogen has been supplemented to the biosphere since the start of the pre-industrial era. One of the most substantial drivers of human-caused change in climatic conditions is enhanced global carbon dioxide emissions.
