All of the following are solutions for reducing air pollution except
a.
increasing the use of clean-burning fossil fuels
b.
decreasing the use of public transportation
c.
using more fuel-efficient vehicles
d.
reducing vehicle emissions

The correct answer is B. Decreasing the use of public transportation

Explanation:

Air pollution refers to the existence of pollutants such as carbon monoxide, sulfur or particulate matter that have a negative impact on the environment and on life including plants, animals and human beings. This type of pollution has multiple causes including the substances released to the air by the factories and other activities such as mining or agriculture. However one of the main causes of air pollution is the burning of fossil fuels in factories and vehicles. Because of this, most of the solutions related to air pollution aim at reducing the burning of fossil which includes reducing vehicle emissions by using fuel-efficient vehicles or clean-burning fossil fuels and most importantly reducing the number of vehicles by promoting alternative means such as bicycle and the use of public transportation. Considering this, the one that is not a solution for air pollution is "decreasing the use of public transportation" as this would lead to more vehicles and therefore more burning of fossil fuels which is the main cause of air pollution.
