In a forum on the impacts of urban expansion on local ecosystems, two ecologists presented conflicting viewpoints. Ecologist A argues that urban expansion is detrimental to local wildlife, leading to habitat loss and a decrease in biodiversity. In contrast, Ecologist B contends that urban areas can actually enhance biodiversity through the creation of gardens, parks, and designated green spaces that provide new habitats and resources for species. The debate centers around whether urban development harms or helps the ecological balance in city environments.
