They believe that small, consistent actions can lead to significant changes, proving that age is not a barrier to making a positive impact on the world.

One major area of focus for these youth-led groups is hands-on community work.

They are showing that you don't need to be a government official or a scientist to contribute; you just need passion and the will to start, proving that collective small efforts create a powerful force for change.
