In today's lecture, we'll discuss the impact of urbanization on local wildlife. One key point is that while some species, like pigeons and rats, thrive in cities, others struggle. A recent study in Melbourne found that the number of native bird species decreased by 30% in areas with high-density housing. However, the presence of even small green spaces, such as community gardens, helped maintain bird diversity. The study also noted that noise pollution affected birds' mating calls, but this had less impact than habitat loss. Therefore, urban planners should prioritize preserving natural corridors.
