GPT explains (level =C2; CEFR aligned): Urban impacts cascade across every spatial tier A city’s metabolic footprint is not confined to its municipal boundary: exhaust emissions foul neighbourhood air (local scale); nutrient‐rich wastewater and heat‐island effects spill into surrounding catchments and regional climate systems (regional scale); and the upstream extraction of energy, food, timber and rare metals reorganises biomes on other continents and perturbs the global carbon cycle (global scale). Consequently, sustainability analysts now treat urban areas as nodal players in a planet-wide socio-ecological network rather than self-contained “dots on a map”.
