Quizplus · Accepted Answer

The carbon cycle is the biogeochemical cycle that has been most interfered with by human actions, particularly through the burning of fossil fuels, deforestation, and other land-use changes. These actions have led to an increase in atmospheric carbon dioxide levels, which contributes to global warming and climate change. The impacts of this on the biosphere include altered distribution and abundance of plant and animal species, changes in food webs, and potentially significant ecosystem collapse.
