帮我写一篇高中英语作文！急！

Dear editor:
I'm writing to tell you something about what I saw while traveling during my holiday .
I was so surprised to find so many immoral behaviors in public.For example ,some people spit everywhere.some travelers scratch their names on the walls ,which does great damage to the buildings .Some people litter here and there .
As far as I'm concerned ,it's time to do something to help improve this situation .First ,certain laws should be passed to prohibit people damaging our environment .Meanwhile ,TV ,newspapers,Internet and other media should also take responsibility to appeal people to be more friendly to our environment .
Most importantly,as travelers ,we should be responsible for what we did in public.Only when each of us is aware of the importance can we make a civilized world .
