CNN Heroes Top 10: Chad Pregracke

Chad Pregracke has made it his life’s work to clean up the Mississippi River and other American waterways. Since 1998, nearly 70,000 volunteers have helped Pregracke and his nonprofit remove more than 7 million pounds of garbage from 23 rivers across the country.

One of this year’s Top 10 Heroes will become the ‘CNN Hero of the Year’ and awarded $250,000 to continue their work.
