cause an imbalance in biogeochemical cycling and lead to problems such as cultural eutrophication and fish kills. Eutrophication is a naturally occurring‚ slow‚ and inevitable process. However‚ when it is accelerated by human activity and water pollution called cultural eutrophication‚ it can lead to the premature aging and death of a body of water. Cultural eutrophication occurs when humans speed up the aging process by allowing excessive amounts of nutrients in such forms as sewage‚ detergents

Human Impact on the Carbon‚ Nitrogen‚ and Phosphorus Cycles Danielle Abbadusky Everest University Human impact on the cycling matter in ecosystems can change a lot of things. Humans can either help or hurt things. The carbon‚ nitrogen and phosphorus cycles are the three cycles of matter in ecosystems. What are these cycles? How do humans effect each one of these individual cycles? What are some examples of humans effecting these cycles? What is the carbon cycle? “Sequence of processes through
