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

Some good news.

London is meeting legal limits for toxic NO2 pollution for the first time – almost 200 years earlier than predicted – following the Mayor’s "world leading air pollution policies," City Hall announces.

The Ultra Low Emissions Zone - and similar policies - really do work.

99% of people breathe air that’s considered polluted. 😷

It damages health, lowers crop yields, deepens inequality and fuels climate change.
