King County wants to honor outstanding efforts to educate youth and protect the environment through the county’s Earth Heroes at School awards program.

Nominations for the 2013 awards are due Feb. 23. Winners will be honored at an event featuring King County Executive Dow Constantine on April 25, during the County’s annual Earth Week celebration.

Recycling, restoring habitat, composting lunchroom waste and growing pesticide-free gardens are among the many types of award-winning projects carried out by students, teachers and staff in King County schools.
