Grammy-nominated musician Jack Johnson has recorded a 30-second song urging listeners to vote "yes" on a Honolulu Charter amendment creating curbside recycling on O'ahu.

The Sierra Club Political Action Committee paid for the ads to be aired during drive times on Honolulu radio station KSSK.

"Reducing the amount of 'opala we send to our landfill is important to me," said Johnson. "Convenient curbside recycling will make it easy for residents to do the right thing."

The North Shore resident and his wife, Kim, founded the Kokua Hawai'i Foundation to support environmental education. And Johnson frequently visits local schools to promote recycling.

According to the Sierra Club Hawaii, 83 million pounds of recyclable material have gone into Oahu's Waimanalo Gulch landfill since the island's curbside recycling plan was scrapped a year ago.
