“Smog irritates the respiratory system, and can reduce lung function, making it more difficult to breathe, especially in children. It also can aggravate asthma and make people more sensitive to allergens, such as dust mites, pets, and pollen, and worsens chronic lung diseases.” said Dr. Thomas Addison, a pulmonologist with Kaiser Permanente San Francisco. “By taking steps to reduce emissions, Bay Area residents help all of us breathe easier.”

Long-term exposure to ozone can reduce lung function. High levels of ozone pollution are particularly harmful for young children, seniors and those with respiratory and heart conditions. Vigorous outdoor exercise should be undertaken only in the early morning hours when ozone concentrations are lower. The Air District issues Spare the Air Alerts whenever air quality is forecast to reach unhealthy concentrations.

A list of simple things the public can do to make clean air choices every day:

  • Bike to work or around town
  • Take public transit
  • Work at home or telecommute
  • Carpool and link your errands to reduce driving
  • Avoid using gas-powered lawn mowers and leaf blowers
  • Reduce household energy use
  • Cook indoors, not on the barbecue
  • Avoid using aerosol spay cleaners, paints and hairspray

Ear to the Wild: The Belted Kingfisher - Gustav’s “Mechanical Bird"

In memory of Gustav Hobel. My friend Gustav and I used to live next door to one another on Sonoma Creek. The Belted Kingfishers would fly by, calling, with that ratchety kind of sound that they have in their voice. That’s why he’d call them the “mechanical bird.”
