1. Yusra Mardini
Mardini is an 18-year-old Syrian swimmer who fled her country after her home was destroyed in the Syrian Civil War. She arrived in Greece with her sister, after making the journey with 18 other migrants — on a boat that was only meant for 6 or 7 people. Somewhere in the Aegean Sea, the boat began to take on water. Along with her sister and two other migrants who could swim, Mardini pushed the boat for three hours until it reached Lesbos. She now lives in Berlin. This year, she represents a part of the first-ever refugee team in Olympic history.
