Amariyanna “Mari” Copeny, known to many as “Little Miss Flint,” is a 14-year-old activist based in Flint, Michigan. Her activism began at just eight years old, when she first became aware of the undrinkable water in her hometown, in which high levels of lead were detected. Copeny began to gain national attention when she wrote a letter to then-President Barack Obama to convince him to come to Flint and see the water crisis firsthand. This letter prompted Obama’s May 2016 visit to Flint. After his visit, he declared a federal state of emergency for the Michigan town and allocated $100 million in aid to address the issue.
