the estuary might be there usual drinking place and due to pollution the water may be contaminated with chemicals causing the animals to die when they drink the water
A wide range of species may be endangered by the pollution of an estuary due to several critical reasons. Estuaries serve as critical nursery grounds for various species such as crustaceans, mollusks, and fish, which rely on the unique salinity and habitat conditions provided by these environments. Pollution introduces harmful chemicals and materials into these environments, disrupting the delicate balance of salinity, reducing water quality, and harming the specialized adaptations that estuary species have developed to survive in such conditions. Moreover, pollution can lead to endocrine disruption which is not fully understood but is known to harm biodiversity by interfering with the reproductive and developmental processes of wildlife. Additionally, habitat destruction, another major consequence of pollution, exacerbates the risk of extinction for many species that depend on estuaries for survival. For example, the alteration of waterways through pollution can hinder the ecological processes necessary for maintaining the biodiversity of estuaries, making these environments uninhabitable for species that once thrived there.
Pollution in estuaries can harm species through chemical contamination, habitat destruction, eutrophication, thermal pollution, and the introduction of invasive species. These factors disrupt the delicate balance of the ecosystem, leading to a decline in biodiversity and the health of aquatic life. Protecting estuaries is essential to maintain the species that depend on these important habitats.
