Fertilizers and sewage can significantly harm rivers by introducing excess nutrients, particularly nitrogen and phosphorus, which lead to eutrophication. This process causes algal blooms that deplete oxygen levels in the water, harming aquatic life and disrupting ecosystems. Additionally, pollutants from sewage can introduce pathogens and toxins, further degrading water quality and posing risks to human health and wildlife. Overall, these contaminants can lead to a decline in biodiversity and the overall health of river ecosystems.
