According to a study conducted by Macquarie University, Sydney's suburbs are undergoing significant changes in their streetscapes, leading to increased density and reduced greenery.
The research indicates that typical knock-down rebuilds are resulting in the elimination of nearly half of front gardens, which directly impacts local biodiversity and urban aesthetics.
Moreover, the study reports that over 60% of the existing tree canopy is being removed, raising concerns about the long-term implications for urban heat management and air quality.
