A group of volunteers gathered at Kaiser Park Saturday to clean up the Coney Island Creek.

Students raked up trash, litter and cleared away debris as part of the fourth annual “It’s My Estuary Day,” a day aimed at raising awareness for the importance of keeping Brooklyn’s waterways chemical- and trash-free.

“Over the last 10 years or so we removed over 25,000 pounds and marine debris from the creek here,” said one volunteer. “We’re trying to bring environmental awareness to the creek.”

The annual event is organized and made possible by several community organizations, including the New York State Marine Association, that care for the park and the environment.

“The important thing we're doing is just making sure that young kids and people walking around know about the environment and how important it is to protect it,” said student Gabrielle Martinez.
