Justification:
-
Fewer vehicles, same number of people moved: A single bus can carry 40–50 passengers who would otherwise need 25–40 separate personal cars/two-wheelers. Replacing many personal vehicle trips with one public transport trip drastically cuts the TOTAL number of vehicles on the road for the same number of commuters.
-
Lower fuel consumption per passenger: Because public transport spreads the fuel cost of one trip across dozens of passengers, fuel consumption (and hence CO₂ and other emissions) per passenger-kilometre is far lower than for personal vehicles, where one or two people consume an entire tank's worth of fuel.
-
Reduced air pollution: Fewer vehicles burning fuel means lower emission of pollutants (CO₂, NOx, particulate matter) into the air — directly reducing air pollution, which is a key form of environmental degradation discussed in the chapter.
-
Reduced congestion and resource strain: Fewer private vehicles also means less traffic congestion, which itself causes further fuel wastage (engines idling in jams) and stress on urban infrastructure and land (roads, parking) — resources that could otherwise serve other uses.
