In the middle of this crisis, one voice broke through – not of a politician, a scientist, or even of a seasoned activist, but of a child determined to be heard. Amariyanna “Mari” Copeny, otherwise known as Little Miss Flint. In 2016, at barely eight years old, Copeny wrote a letter to President Barack Obama. She told him what life in Flint had become for kids like her: what it meant to grow up in a city where ...
