Urbanization has a profound effect on wildlife primarily by disrupting habitats and fragmenting ecosystems. As cities expand, the natural landscapes that serve as homes, breeding grounds, and food sources for various species are altered or destroyed. This fragmentation leads to isolated patches of habitat, making it difficult for species to migrate, find mates, and access the resources they need to survive.

The changes brought about by urban growth, such as the construction of buildings, roads, and other infrastructure, can create barriers that wildlife may struggle to cross. This can lead to decreased genetic diversity among populations as they become isolated from one another. Moreover, urban areas often introduce new challenges for wildlife, including increased human activity, pollution, and competition with invasive species. As ecosystems are disrupted, many species may decline or become endangered due to their inability to adapt to these rapid changes in their environment.

The notion that urbanization creates new habitats is inaccurate because, while some species may thrive in urban settings (often generalists that can adapt to human-altered landscapes), this does not compensate for the overall loss and degradation of natural habitats. Additionally, suggesting that urbanization has no significant impact on wildlife overlooks the extensive scientific research documenting these negative effects. Lastly, increased biodiversity is typically not a result of urban
