In the first passage, the author argues that urbanization has led to a significant decline in biodiversity, citing studies that show species extinction correlating with urban expansion. The author emphasizes the need for sustainable development in urban planning to mitigate this issue, advocating for the integration of green spaces in city designs.

In the second passage, another author takes a different approach. This author points out that while urbanization may pose risks to biodiversity, it can also lead to increased environmental awareness and cooperation among communities. The author presents examples where urban populations have successfully initiated conservation projects within city limits, highlighting the potential for restoring local habitats through urban interventions.

Both authors address the impacts of urbanization on biodiversity but draw contrasting conclusions regarding the implications for conservation efforts.
