I'd like to telling you something about the problem of pollution we were facing. As we know,
the factory besides our school gives off heavy smoke all day long. very loud noise hurts for our ears.
Rubbish and waste are thrown here or there. It also sends out polluted water and poisonous gas. All
these has done great harm to the healthy and study of the students. But as time goes on, little has
done to change the situation.1 don't think we can study well if the problem is solved. We do hope
you'll help and support me.
