lungs2How clean is the air you breathe? If you live in a city, I'm sure you notice the difference as soon as you venture into the suburbs; air becomes easier to breathe and might even have a sweet scent! The American Lung Association's list of U.S. cities with the cleanest air made me realize I don't recognize most of these cities. Does fewer humans mean less pollution? Today Canada celebrates Clean Air Day, but you can join in no matter where you live. How can you (or do you) support cleaner air where you live? Some ideas are to bike more, carpool to work, or live closer to work. While we're on the topic of breathing, what's with this Asthmatic Playpen?! I'm not a child, but I want to sit in there.
