The main impact of pollution on biodiversity is the degradation of habitats and the decline of species populations. Pollution, including chemicals, plastics, and waste, can lead to soil and water contamination, adversely affecting wildlife health. It disrupts ecosystem functions such as nutrient cycling, and can cause loss of habitats, which further threatens species survival. Polluted environments may lead to altered reproductive success and increased mortality rates among sensitive species. Ultimately, this results in decreased biodiversity, threatening the resilience of ecosystems and impairing their ability to provide vital services.
