CNN Hero of the Year: Chad Pregracke

Anderson sat down with Chad Pregracke, of East Moline, IL, immediately after revealing his selection as 2013 CNN Hero of the Year.

Pregracke has dedicated his life to cleaning up the Mississippi River and other American waterways. Since 1998, nearly 70,000 volunteers have helped Pregracke and his non-profit remove more than 7 million pounds of garbage from 23 rivers across the country.
