Today in our environmental science lecture, we're discussing urban green spaces. A recent study in Melbourne found that adding more parks and community gardens can reduce the city's average temperature by up to two degrees Celsius during summer heatwaves. The study also highlighted that these green areas improve air quality and mental well-being. However, the researchers noted that the benefits depend on the size and connectivity of the green spaces. Small, isolated parks have a limited cooling effect, whereas large, interconnected networks of green areas are most effective. The city council is now planning to expand its existing park network by 30% over the next five years.
