Rapper Macklemore is going green in support of a new campaign to clean up the Duwamish River in Washington.
The river runs through the star's native Seattle and he is fronting a new drive to help protect the water source from pollution.
The River for All scheme urges local officials to clean up the Duwamish after it was listed as one of the most toxic sites in the U.S.
MACklemore says, "Recently I had the opportunity to meet with community leaders to learn about a deeply important local resource to our city that has been sorely neglected, the Duwamish River... I was alarmed, however, to learn more about the river's current state and negative impact on our city's public health... I believe that it is our responsibility as members of Seattle to clean and restore this river back to health, and to make sure that All children can grow up and have access to a clean and safe environment...
"We are Seattle. No bridge, boundaries or invisible man-made lines divide us. This is our home, our people and our community. This is our city's only river."
