Humans can promote the carbon cycle by adopting more solar energy and decreasing in fossil fuels burning or applying wind power. We can also cut down less trees in the forests because it uses carbon dioxide in phothosynthesis in making glucose. Interaction of humans with carbon cycle is of different angles. In exhalation, we exhale carbon as carbon dioxide. When human expires, our bodies will decompose and carbon is liberated into the soil. Also by burning fossil fuels for electricity and transportation usage, carbon is lifted through the carbon cycle.
