一篇3~5分钟的英语演讲稿,内容要是向上的,最好是关于环境保护的.

　　Good morning!Ladies and gentlemen,
　　Today,I am going to make a speech here.My topic is how to proctect environment.
　　Our environment is very important for our lives.Good environment makes us fit and happy.In the past,there were many trees around us,the air was fresh and the river was clean.But now,things change bad.People cut down trees without limitation.Air pollution and water polloution are very serious .The environment around us becomes very terrible.Therefore,we have to stop it and begin to protect our environment.
　　First,we should plant more trees to keep water,which can also make our city beautiful.Second,we can ride a bike or walk to the school and work.In this way,we not only save energy,but also reduce the air pollution.Third,we should stop factories from pouring waste water into the river and waste gas into the air.Fourth,protecting environment should start with me.It's every one 's duty to protect the environment.Whenever we see litter on the ground,we should pick it up and throw it into dusbins.Never spit in public.Don’t draw on public walls.
　　All in all,a good environment is very important for us.We should summon more people to protect the environment.
