Indoor Air Quality. Alaskans spend a lot of time indoors. Unfortunately, indoor air can have even more pollutants than outdoor air. Activities like heating, cooking, bathing, and even breathing can all impact indoor air quality. Indoor air pollutants can be chemicals, gases, and living organisms like mold. Other pollutants cause or worsen allergies, respiratory illnesses (such as asthma), heart disease, cancer, and other serious long-term conditions.
The number of large wildfires — defined as those covering more than 1,000 acres — is increasing throughout the region. Over the past 12 years, every state in the Western U.S. has experienced an increase in the average number of large wildfires per year compared to the annual average from 1980 to 2000.
