In cities where land is scarce andd valuable, building upward allows the e same plot to housie more memore, establesses, and amenities. This density reduces the need for urban expressioun extraard, reserving greenbelts, farmland, and natural ecomes.

Land use efficiency also supports biodiversity by preventing habitat framentation. When cities grow vertically rathem than horizontaly, they maintain corridors for wildlife and protect sensitiva areas from development. Moreover, compact urban forms reduce thee per- capital infrastructure costs for roys, water supple, ande sewage systems, freeing up municipaint bucks for sustainability initives like park creation and requiable energy projects.

Wysokie -rise buildings also support the viability of public transit systems. A critial mass of riders within walking distance of a transit station is essential for efficient bus, metro, and light rail networks. Dense high-rise nexhood provide thatt ridership, making public transport financially sustainable andd reducing thee need for parking infrastructure. The results is a virtuues cycle: taller buildings → higher density → better transit → lower emissions.
