Volunteers in the Bronx teamed up in an international effort to clean up the environment.

Roughly 50 people spent Sunday on the water cleaning up sites throughout Pelham Bay Park.

The volunteers teamed up with the Parks Department to collect everything from tires and car bumpers to cans and bottles.

The Hutchinson River Restoration Project has been organizing the annual cleanup for eight years. The group has its own solar-powered boat known as the "Anne Hutchinson."

"I really wanted to find out if there was a group doing something about the state of the river here, and that's when I found the Hutchinson River Restoration Project," says volunteer Matthew Umbro.

Volunteers put an emphasis on making sure the Thomas Pell Wildlife Sanctuary stays clean because there are many endangered species that call the area home.

Other groups like Save The Sound and the American Littoral Society participate in the international coastal cleanup as well. They tally how much and what kind of litter they collect and provide that information to the Ocean Conservancy. Organizers say that data affects legislation.
