Okay kiddo, so there are these fancy meetings called Pugwash Conferences where really smart grown-ups from all over the world come together to talk about science and how it affects the world. They talk about things like how to make sure people are safe from dangerous weapons and how we can use science to help our planet stay healthy.
These grown-ups also try to find ways for different countries to work together nicely and not fight with each other. They believe that if everyone talks and listens to each other, then we can all live in a peaceful world.
Think of it like a big playdate where all the adults are trying to be friends and come up with ways to help everyone get along and stay safe. It's important work that helps us all have a better future!
