Can Albatrosses Detect Illegal Fishing in the Southern Ocean?

Giant seabirds and shellfish are being used to help protect our planet.

On an tiny island in the remote Southern Ocean, a French researcher wanted to find out why so many birds were being killed by fishing boats.

By attaching radar loggers to Albatrosses, he inadvertently invented a powerful method for tracking down illegal vessels.

And in New Orleans in the US, a restaurant owner is recycling tonnes of old oyster shells.

They’re being put back in the ocean to protect the shoreline and create new reefs so more oysters can grow.
