Volunteers have been doing battle with litter along the Antonine Wall.
The Roman fortification, which ns 37 miles from Bo’ness to Old Kilpatrick, was chosen as the launch site for National Spring Clean 2009.
Schools, youth clubs, community groups and individuals will be involved in litter picks across the country over the next month.
So far, more than 35,000 people have signed up for the Spring Clean, organised by Keep Scotland Beautiful.
John Summers, chief executive of Keep Scotland Beautiful, said: “It is amazing to see today, what the Romans achieved by working together, and if we do the same, work together to combat littering, then maybe we can leave a legacy of a litter-free Scotland.
National Spring Clean 2009 is a great opportunity for groups of people to really make a difference to the environmental quality of Scotland.”
Environment Secretary Richard Lochhead added: “Scotland’s natural environment is worth around £17bn to our economy and the cost to our local authorities for street cleansing alone is now over £100m per annum.
“Litter is a problem which cannot be ignored.
“We want as many people as possible to get involved in this year’s campaign. It offers people throughout Scotland the opportunity to restore a sense of community pride and clean up their neighbourhoods for themselves and visitors to our country.”
Meanwhile, a campaign to encourage people to reduce, reuse and recycle the packaging that comes with their everyday products has been launched.
The initial stages of the Positive Package drive will focus on Easter egg wrapping.
Environment Minister Roseanna Cunningham launched the campaign at Oakbank Primary in Perth.
She said: “Packaging is a key area in relation to waste. Some packaging helps protect products and can make them last longer, which can reduce waste. Equally, though, excess packaging is wasteful.”
Dr Nicki Souter, from Waste Aware Scotland, said: “There are many things we can all do to limit the amount of waste that packaging generates, such as looking for products with less packaging or reusing things like carrier bags and refillable products.
“Over and above that, we can also all recycle more of our packaging, as this can then be used again to make new products.”
