What is the main consequence of improper sewage disposal?

The main consequence of improper sewage disposal is environmental contamination. When sewage is not managed correctly, it can lead to the release of harmful pathogens, chemicals, and nutrients into the environment. This contamination can adversely affect water sources, soil, and ecosystems, harming aquatic life and potentially leading to serious public health risks. Contaminated water can become a vector for diseases and can render natural resources unusable for drinking, recreation, and agriculture.

In contrast to the correct answer, increased soil fertility, health benefits to wildlife, and improved property value do not accurately represent the outcomes of improper sewage disposal. Although nutrients from sewage might temporarily increase soil fertility, the overall ecological damage and risk to human health greatly outweigh any perceived benefits. Wildlife is more likely to suffer than benefit from contaminated environments, as their habitats can be degraded and food sources compromised. Property values typically decrease in areas where sewage disposal is improperly managed due to health risks and environmental hazards, emphasizing the importance of proper sewage practices to protect both the environment and public health.
