Good morning, everyone. Today we're going to discuss the impact of urbanization on local wildlife. A recent study conducted in Melbourne found that while some species, like possums and ravens, have adapted well to city life, others, particularly ground-nesting birds, have declined sharply. The study also noted that the presence of small green spaces, such as community gardens, can significantly boost biodiversity. However, the key factor for survival is not the size of the green area, but its connectivity to larger habitats. Without this, even well-vegetated urban parks fail to support many native species.
❓ According to the lecture, what is the most important factor for wildlife survival in urban areas?
A. A. The size of green spaces
B. B. The connectivity between green spaces and larger habitats
C. C. The presence of community gardens
D. D. The type of native species
✅ 正确答案
B. The connectivity between green spaces and larger habitats
