Cities can't do it alone, however. Everyone can make simple choices that will curb the pollution problems. Following regular maintenance, avoiding jackrabbit starts and stops, turning off the engine during lengthy waits, and keeping tires regularly inflated reduce your car's emissions significantly. Observing ozone alert day restrictions help as well. Air pollution can make you sick and shorten your life.
Some pollutants cause cancer, birth defects, nerve damage and lung damage.
But pollution doesn't have to be ever present. Let's all do our part to curb air pollution from our cars and trucks.
