 induce excessive algal growth. The major causes of nutrient pollution are anthropogenic fertilizers, sewage, and industrial wastewater discharged into the environment. Thus, nitrogen is the focus of this set of indicators: “Filtration of surface water by ecosystem types”. Clearly, we would hope that the areas where nitrogen pollution is highest are also the areas where nature can most effectively filter it out. However, this is not always the case. It is thus important to examine how the two indicators in this set compare with one another.
