Explain how human activities can cause an imbalance in biogeochemical cycling and lead to problems such as cultural eutrophication and fish kills.

Biogeochemical cycles are the normal patterns of natural phenomenons that occur in the earths spheres, interacting and interdepedent. These cycles help to sustain life on earth as well as to maintain the resources that provide energy. When man-made structures and technologies are put into action, they distort the natural state of these said cycles causing them to rapidly occur or to forcefully be available. The result also of pollution and the increase in greenhouse gas.
