So, you know how sometimes when we run around and play, we get all hot and sweaty and we need to take a break to catch our breath? Well, the same thing can happen to big cities, like Paris!
"Paris Breathes" is a program that helps make the air in Paris healthier by making it easier for people to walk, bike, and take public transportation instead of driving cars. When lots of cars and trucks drive around, they create something called "air pollution," which can make it harder for people to breathe and can even make plants and animals sick.
So, by encouraging people to use alternative forms of transportation, Paris is taking a big breath of fresh air and helping to keep everyone and everything healthy!
