Contaminated runoff from paved surfaces pollutes Oregon's rivers and lakes and contributes to flooding. Weed killers used along roads also pollute our waters. If improperly disposed, oil from just one oil change can contaminate a million gallons of fresh water. Cars kill more animals than hunting and animal experimentation combined, and roads fragment animal habitat. Many were pedestrians or bicyclists.
Car crashes are the number one cause of death for children nationwide.
Ninety-nine percent of automobile trips include no charge for parking. However, neither land nor pavement are free, and the expense of parking is incorporated into other costs. Space could be used more efficiently if businesses with different busy periods shared parking. Pavement also has a major impact on water quality. Dirt, motor oil, and household chemicals are washed off pavement into our streams and lakes.
