Today, in our environmental science lecture, we're discussing urban green spaces. A recent study in Melbourne found that adding parks and community gardens can reduce the city's average temperature by up to two degrees Celsius. This cooling effect occurs because plants release moisture through transpiration, which lowers surrounding air temperature. However, the study highlighted that the distribution of these spaces is uneven, with wealthier neighborhoods having 40% more green coverage than lower-income areas. This disparity leads to what researchers call 'thermal inequality,' where poorer residents experience higher heat-related health risks during summer. To address this, the city plans to plant 5,000 trees in underserved districts by 2028.
