Clean up the countryside society
Vicki was coming from her small country school and it was one of the last days of the
term. There was sun in the sky and the birds were singing their beautiful songs. Vicki
loved the countryside and she had lived there all her life, The weather was so nice that
Vicki decided to take a longer way home, to the cottage where she lived. On her way
she passed through a littlgrove where she used to play. Vicki was shocked to see that
the grove looked terrible: it was piled with rubbish. Vicki ran all her way back home. She
had to do something about this mess.Suddenly she had an idea .She would start her own
Clean up the Countryside Society.
When Vicki got home she phoned four of her school friends- Alice, Rosie, Cathy and
Jane. They all agreed to meet her at the grove.The girls set to work filling big black plastic
bags with rubbish. It was hard work but soon all the rubbish was cleared away and the
forest looked beautiful again.
On the next day the society had another meeting. Vicki said, “Today we must
watch for rubbish dumpers.” Everyone agreed and soon Rosie and Jane noticed some
picnickers. The picnickers were finishing their picnic and they left all their rubbish on the
ground.“What are you going to do with all that litter you’ve left?”Asked the girls. “I don’t
know what you mean, » said a tall man with an American accent. “Just think, » said the
girl. “Think about those bits of glass that you have left from your bottles of juice, of all
those cola cans and think about how ugly the place will look littered like that.» The
young lady is right, » said a woman with a little hat on. “We just can’t leave this
rubbish here. » That’s right, » said Vicki. “Here take this bag. » Thank you, girls, » they
said, “for helping us understand that the country is a beautiful place and that we must
not spoil it. » Then they all got into their American car and drove to the city. Vicki
and her friends shouted, “Three cheers for our Society! Hip Hip Hoorah! Hip Hip
Hoorah! Hip Hip Hoorah! ”
You can imagine how surprised the girls were when the next morning their Science
teacher, Mr. Bird, spoke to the class about ecology and the importance of keeping the
environment clean. He said that pollution was getting worse and worse which could easily
bring us to a global disaster. The result of the environmental crisis was that in many parts
of the world humans were beginning to suffer from shortages of food and clean water
to survive. But Mr. Bird said there was always hope. People had already learnt some
important rules to protect the environment.-
