    Chicago Clean Air Resilience Network Launches to Expand Nonprofit Access to Clean Air Equipment and Free N95 Masks

    What a year! Looking back and looking forward, from PHAN CEO Tarz Ludwigsen

    Picture of the earth against the dark of space. Text on top is in red: "public health in the U.s. and globally is heading in the wrong direction" Text below: PHAN believes that the current approach to public health, both in the U.S. and globally, is heading in the wrong direction, and it will result in more airborne pandemics that will be even more severe than COVID. We call on public health officials around the world to support vaccinations and protections from airborne pathogens.

Text reads I saw my first tornado that summer, but even in the absence of 150 mile per hour winds, the daily winds of 20 mph still remind you just how small you are on this planet... I had to relearn life in a new reality.
