Pollution is one of the biggest problems that our world faces .As the world becomes more industrialized and as cars are increasing every day ,the problem of pollution will become more serious . Our class decided to wage war against it .The first thing we did was to have a clean-up day. We devote that day to picking up all the litter that we find in our school and in the streets near the school .
We also made posters which we put up in the whole district about how to keep the place around you clean and healthy . we started a campaign to encourage people use bicycles instead of cars .
