YOUR report of the damage litter is causing to one of our nation's most treasured beauty spots will have struck a chord with your readers, just as it did at Keep Scotland Beautiful ("Warning major litter problem is ruining Loch Lomond views", The Herald, April 10).

Earlier this month Keep Scotland Beautiful's mass-engagement campaign, Clean Up Scotland, reached 40,000 pledges from people across Scotland determined to show they care about where they live, work and enjoy their leisure. They've signed up to the Clean Up Scotland pledge in order to claim back their streets and parks, look after them and stop dog-fouling, graffiti, littering and fly-tipping.

The chairman of the Friends of Loch Lomond and the Trossachs, James Fraser, is spot on in his comment that more needs to be done. I also sympathise with Argyll and Bute Council when it confirms its weekly litter clearings of the A82.

This is a big year for Scotland, and that's a major reason why we launched the Clean Up Scotland campaign. When Glasgow hosts the Commonwealth Games in July, the world will be watching in numbers we've never experienced before. Through community clean-ups such as those organised by Clean Up Scotland, we can have a clean and welcoming country.

It's vital that individuals take responsibility for their litter, with local people doing something to improve the environmental quality of their local neighbourhood. Our army of 40,000 pledgers are changing long-term behaviour by making littering unacceptable.
