IMAGINATIVE measures are needed to combat the 'chewing gum trail of shame' (July 23).

Vast entrepreneurial opportunity awaits someone who sets up a service which traces the original owner of the now discarded gum.

York's proximity to science labs means a tiny sample of each piece of gum on our city streets could be DNA profiled.

MP Hugh Bayley could lobby for the introduction of a new law - say "the irresponsible ejection of gum" - which would oblige the chewer of said gum to ensure its appropriate disposal.

DNA matching would lead to a fine dropping through the letter box. Carried out nationwide, this would raise millions and easily pay for the national removal of gum from our streets.
