Transportation is the single largest source of nitrogen oxides and carbon monoxide.
These compounds pollute the air and cause acid rain. While the smallest reduction may seem insignificant to you, it can make a big difference for future generations. Fortunately, there are ways to ease this problem through ridesharing. Ride your bike. And if you have to drive, make sure you give your vehicle regular tune-ups.
