Today in our environmental science lecture, we'll discuss the impact of urban green spaces. A recent study in Melbourne examined three parks over a year. Researchers measured temperature, noise levels, and biodiversity. Surprisingly, the smallest park, though only two hectares, had the highest bird species diversity. This was due to its variety of native shrubs and an old pond. However, the largest park, at ten hectares, showed the greatest cooling effect, reducing nearby temperatures by up to three degrees Celsius. The study concluded that size matters for cooling, but habitat complexity is key for wildlife.
