In today's lecture, we'll discuss the impact of urbanization on local wildlife. A study in Melbourne found that while some species, like possums, adapt well to city life, others, such as certain birds, struggle due to habitat loss. Interestingly, the research showed that green roofs and community gardens can significantly increase biodiversity. For example, a project in the city center introduced native plants on building rooftops, which attracted over 30 new insect species within a year. However, the lecturer emphasizes that these efforts require ongoing maintenance and public support to be effective.
