For years, US embassies in foreign countries kept a close eye on the air quality. They shared data on pollution to keep Americans living abroad safe. During the Trump administration, this program was changed and eventually stopped.
A new study found that air pollution actually got worse in those cities once the monitoring stopped. Researchers think this happened because local governments stopped feeling the pressure to clean up the air. When the US government tracks air quality, other countries pay more attention.
The study looked at several major cities. It found that the air became dirtier after the US stopped publishing the data. Breathing in dirty air is bad for your lungs and your heart. Experts say that having this information is an important way to make sure people stay healthy.
Now, there are questions about whether the US should restart this program. Many people say that being open about air pollution helps everyone breathe easier.
