9. Coco Gauff
Gauff is just 16 years old, but she’s on the way to becoming one of the biggest sports stars in the world. She looks set to inherit Serena Williams’ mantle as a female superstar and also as a civil rights leader. Gauff has used her platform to speak out against brutality towards black citizens in the United States.

In a video, she referenced a number of unarmed black Americans who died in recent years at the hands of authorities or white fellow citizens. Gauff wrote: “Am I Next?” in a haunting message that sums up exactly how grim the situation is for many people in America.
