Stella Bowles, M.S.M.
Upper LaHave, Nova Scotia
Elementary school student Stella Bowles studied the contamination of the LaHave River near her home for a science project. When she discovered that untreated sewage was polluting the river, she used social media to gather support to have it cleaned up. As her online following grew, the media took notice and, eventually, all three levels of government pledged funds toward improving the water quality.
