Brightline Defense Air Quality Short Story
Executive Director Eddie Ahn of Brightline Defense is a passionate advocate for the underserved of San Francisco. We climb up to the roof with he and his team as they install an air quality sensor near a busy City freeway interchange so that it can start monitoring pollution there. Data collected by the nonprofit's network of instruments is available for free to low-income residents who cannot afford their own sensors. Brightline partners with other groups to get the word out about protecting everyone from unhealthy air.
