Which of the following is an effective way to reduce air pollution?
Answer and explanation
Correct answer: Using public transport
Public transport allows many people to travel in one vehicle, so it can replace some separate private-vehicle trips. Fewer vehicle trips generally mean lower fuel consumption and fewer exhaust emissions. Burning waste, dumping it in rivers, and cutting trees damage the environment rather than reducing air pollution. The benefit is greatest when public transport is efficient and widely used.
