IT is art you can view at your own convenience - but it has an important environmental message for all.

The toilets at Sutton Bank visitor centre, on the edge of the North York Moors, have taken on a colourful hue, thanks to pupils from Thirsk School Wildlife Club.

Working with the national park's education service, they have produced art to show people where the water for the toilets comes from - and what happens to it when you flush.

Other panels show how important clean water is to wildlife in rivers and how to conserve supplies.

Teacher Mark Oates, who runs the club, said yesterday: "The pupils have shown great energy and creativity.

"They have enjoyed the designing and painting and have also learnt a lot about the importance of water in the environment."

National Park education officer Sue Whitehouse said: "The entire project was done in the pupils' own time, out of school hours, and we are delighted with the results."

The authority plans to involve the club and other youngsters in getting the conservation message across throughout the park.
