Urban runoff has detrimental effects on aquatic ecosystems due to its toxic nature. The introduction of pollutants can lead to the degradation of water quality, resulting in the loss of biodiversity. For instance, increased levels of nutrients from runoff can cause eutrophication, leading to algal blooms that deplete oxygen levels in the water and harm aquatic organisms. Moreover, the presence of toxic chemicals can disrupt the reproductive systems of fish and other marine life, threatening entire populations.
