Today we're discussing the impact of urbanization on local wildlife. A recent study in Melbourne found that while some species, like possums, adapt well to city life, others, such as certain birds, struggle due to noise and lack of natural nesting sites. Interestingly, the research showed that green roofs and community gardens can significantly boost biodiversity. However, the most surprising finding was that small parks connected by tree-lined streets were more effective than one large park. This is because they allow animals to move safely between habitats, reducing genetic isolation.
