KEEPING ISLES BEAUTIFUL

JOIN O'AHU CLEANUP EFFORTS SATURDAY

"Green starts with us." That's the theme of the ongoing Great American Cleanup, organized by Keep America Beautiful. On Saturday, Keep the Hawaiian Islands Beautiful Day, volunteers will take part in efforts ranging from shoreline debris removal to community garden cultivation. Among the plans for O'ahu are a storm-drain stenciling in Honolulu Harbor and a cleanup at Hanauma Bay.

Volunteers for the stenciling project dubbed Stop The Ocean Pollution will meet at 10 a.m. at Pier 7. S.T.O.P. partners will manage the project focusing on the makai end of the watershed, which flows directly into the harbor.

Friends of Hanauma Bay will roll up their sleeves for a cleanup set for 8:30 to 11:30 a.m. They'll supply gloves and trash bags as well as cool drinks.
