Haunted Waters

There are warm ocean waters and beautiful views on the western coasts of Greece. But the area has a problem. Many of its beaches are cluttered with metal, plastic, and fishing nets.

The trash comes from abandoned fish farms. These are huge pens where fish are raised for food. Fish-farming companies leave them behind when they go out of business.

Healthy Seas is an ocean conservation group. It has a nickname for these abandoned places: ghost farms. In 2021, the group started Operation Ghost Farms. It’s a fish-farm cleanup effort in Greece. So far, Operation Ghost Farms has cleared more than 310 tons, or 620,000 pounds, of debris.

Taking Back the Beach

Ghost farms are ugly. They’re also dangerous. Swimmers can hurt themselves on the debris. Marine animals can get tangled in the nets. Plus, trash-filled waters are bad for tourism. And they make it harder for fishermen to make a living.

These hazards inspired Operation Ghost Farms. According to the Healthy Seas website, the project aims to “rejuvenate rejuvenate to make something fresh or new again (verb) local ecosystems, support affected communities, and raise awareness of the broader environmental impact.”

In 2021, residents of a Greek island called Ithaca reached out to Healthy Seas. “They told us, ‘There is a mess here,’” Samara Croci told TIME for Kids. She’s the communications manager for Healthy Seas. The Ithaca locals said a fish farm had shut down 10 years ago. The equipment was still sitting in the water. It was “spreading everywhere,” Croci says.

Healthy Seas organized an eight-day cleanup. There were 45 participants. Among them were 20 divers. They plunged into the water to extract the old fishing equipment. The first operation collected more than 167,000 pounds of garbage. That included nearly 84,000 pounds of plastic.

Rising Tide

Healthy Seas is still leading cleanups. First, the group finds abandoned fish farms. Then group leaders talk to local authorities. They have to get permission to do a cleanup. Healthy Seas then recruits volunteers. After the cleanup, the group clears the trash. Volunteers recycle as much of the recovered equipment as possible.

Healthy Seas likes to teach young people about keeping beaches clean (see “Making a Difference”). It also raises awareness of the problem. “There is no accountability for [companies] to clean up before they leave,” Croci says. So the group hopes to create “guidelines of how the legislation legislation a set of laws created by the government (noun) should change,” she adds. For example, the government could start by making stricter policies to reduce ghost farms. “Then,” Croci says, “we will try to push it little by little.”

Healthy Seas runs Operation Ghost Farms. The group also raises awareness of other problems affecting the world’s oceans. Healthy Seas believes this awareness starts in schools. The group works to boost “ocean literacy,” to get kids involved.
