Smoke from cars and coal creates tiny, invisible "dust" in the air. This toxic air travels into our bodies, causing heart problems, asthma, and even memory loss.19 cities (like London and Beijing) proved we can fix this. They added more electric buses, built safe cycle lanes, and stopped people from burning coal at home.Because of these changes, the air is now 20% to 45% cleaner. This saves millions of lives and helps kids grow up with healthy lungs.
