I live in a very old town which is surrounded by beautiful woods.
It is a famous beauty spot.
On Sundays, hundreds of people come from the city to see our town and to walk through the woods.
Visitors have been asked to keep the woods clean and tidy.
Litter baskets have been placed under the trees, but people still throw their rubbish everywhere.
Last Wednesday, I went for a walk in the woods.
What I saw made me very sad.
The litter baskets were empty, but the ground was covered with pieces of paper, cigarette ends, old tyres, empty bottles and rusty tins.
Among the rubbish, I found a sign which said, 'Anyone who leaves litter in these woods will be prosecuted!'
I looked round.
The sign had been broken.
I smiled.
You see, the woods are the only clean place in our town — on the sign.
