How are humans affecting the natural course of the biogeochemical cycles? Why? Provide 3 examples to explain your point of view.

Examples

burning of fossil fuels, the deforestation and combustion of biomass

Human activities have greatly increased carbon dioxide levels in the atmosphere and nitrogen levels in the biosphere. Altered biogeochemical cycles combined with climate change increase the vulnerability of biodiversity, food security, human health, and water quality to a changing climate.
