Why should anyone else care about what I do with my sewage on my own property? Integrate specific examples from course material in your response. Solution Anyone is going to care what you are going to do with house hold sewage generation and disposal of sewage into the environment because sewage may causes high environmental problem - climate change due to presence more non-degradable phosphorous & organic compounds. Human impacts on environmental change via sewage are leading to the following imbalance in the ecosystem at trophic levels. Household-sewage and toxic lead pollutants are other factors responsible for death of the photosynthetic microalgae & macroalgae result in dead zone with photosynthetic biomass. This dead zone formation is mainly have higher impact on nitrogen cycle level of water and nitrogen cycle is going to increase due to higher farm fertilizers mixing into the aquatic zone via storm water finally bacterial activity is going to reduce “dissolved oxygen level” available to the other aquatic species dramatically via aerobic respiration.
