Pollution has a significant impact on aquatic life. It can lead to water contamination, reduced water quality, and habitat degradation, which can harm fish, algae, plants, and other organisms living in water bodies. Pollutants such as heavy metals, chemicals, plastics, and excess nutrients can disrupt the food chain, decrease oxygen levels, and result in the decline of aquatic populations. Long-term exposure to pollution can also lead to genetic mutations, reproductive issues, and even death in aquatic species. Overall, pollution poses a serious threat to the health and biodiversity of aquatic ecosystems.
