Passage 1 discusses the impact of urbanization on local wildlife populations, highlighting the decrease in common bird species as cities expand. It suggests that habitat fragmentation and increased human activity lead to lower biodiversity.
Passage 2 focuses on the benefits of urban parks, arguing that green spaces can help mitigate some negative effects of urbanization. It claims that parks serve as important refuges for wildlife and encourage the presence of species that might otherwise be absent in heavily developed areas.
