The Los Angeles County Department of Beaches and Harbors invites local third-, fourth- and fifth-graders to join the fight against ocean pollution with its annual “Can the Trash!” poster contest. Kids are asked to draw a poster conveying a message about how people can keep beaches and oceans free of pollution. Contest deadline is Jan. 12. Winning artwork will be featured on Los Angeles County beach trash barrels next summer. For entry details and a helpful video, visit beaches.lacounty.gov/postercontest.
