Could swimming the Channel be banned?
French authorities are looking to ban swimmers from trying to cross the English Channel.
It's because the stretch of water between England and France is the busiest in the world for ships. More than 500 pass through every day.
The swim's got so popular there are safety fears that too many people are swimming in the busy shipping lanes.
The French banned swimmers starting the journey from their side 17 years ago, but now they want a total ban.
