The primary impact of pollution on freshwater resources is the degradation of water quality, which affects both human health and aquatic ecosystems. Contaminants such as heavy metals, nutrients, and plastics can harm aquatic life, disrupt food webs, and diminish the availability of clean water. Polluted freshwater sources may lead to toxic algal blooms, harming fish and other organisms and making water unsafe for human consumption. Addressing pollution requires integrated approaches to watershed management and pollution control to protect these vital resources.
