Michael Palin has said that children must go on geography field trips to fire their imagination.
The globetrotting TV presenter believes it vital that pupils see the natural world and said that they leave the classroom less often nowadays.
Ahead of a speech on geography to the Prince's Teaching Institute this week, Mr Palin said his love of the subject came largely from the chance to "get out of the building". He added: "It's different now, partly because people have laptops and don't have to go out. We need to ensure that good teachers can fire the imagination of the children."
