What You Do Actually Does Matter
The actions of individuals do make a difference. On a day-to-day level, the easiest and best thing a person can do to reduce air pollution is to avoid driving. By walking or biking instead of operating a vehicle, you are lessening your impact dramatically. Vehicle emissions are a significant contributor to air pollution, so not using your car makes a difference.
However, if you can’t walk or bike, taking public transportation can help. Most buses can hold at least 40 passengers, potentially taking 40 vehicles off the road.
If you simply must drive, consider an electric car. In comparison, its impact on air pollution levels is substantially lower.
