The release of untreated dye effluents from textile factories is a major source of aquatic pollution. These toxic substances reduce oxygen levels in the water, making it difficult for fish and other aquatic organisms to survive. Heavy metals and hazardous chemicals accumulate in river sediments and can enter the food web, leading to health problems for animals and people alike. In developing regions where environmental regulations are lax and communities depend on local waterways, the consequences are particularly dire, demonstrating how fast fashion’s environmental impact can devastate entire ecosystems.
