This #WorldChildrensDay, let's remember how important #CleanAir is for children. As pediatric infectious disease specialist Dr. Paul Lewis (Oregon, U.S.) stated, “Children are like hummingbirds; they breathe quickly and, for their size, end up with more #pollution in their lungs than adults.”

For the first time, #SoGA2025 includes air pollution's impact on dementia. Growing evidence suggests poor #AirQuality can progress and worsen neurological diseases - diminishing people's quality of life and causing premature death. @heisoga.bsky.social#SoGA2025#AirQuality Read the report: https://bit.ly/42PslPQ

#ThrowbackThursday! Winter 2016 - 12 OpenAQ Community members from 10 countries + anonymous co-authors shared OpenAQ’s view on the importance & power of open air quality data in the Clean Air Journal. "To combat air inequality, governments & researchers must open their data." bit.ly/48R7vDu
