Today we'll discuss the impact of urbanization on local ecosystems. A key point is that while cities often reduce biodiversity, they can also create new habitats. For example, green roofs and vertical gardens provide shelter for insects and birds. However, these artificial habitats differ from natural ones in terms of species composition. A study in Berlin found that green roofs supported more beetle species than expected, but fewer native plant species. Interestingly, the researchers noted that the age of the roof mattered: older roofs had richer biodiversity. Therefore, urban planners should consider the long-term development of these spaces.
