为迎接世界环境保护日（6月5日），你校举行环境保护活动，倡议大家为保护城市环境，从自身做起，请你根据下面提示写一篇80词左右的广播稿。
提示：Why to protect the environment：每个人都生活在这个城市里
Shouldn't：不要乱扔垃圾（当地面上有垃圾时，应该捡起来）；不要随地吐痰；在公共场所不要抽烟等
Must：保护花草树木，阻止人们污染河水
Wish：城市变得更加美丽
Good morning, everyone! We are all living in this city. It's our duty to keep it clean and tidy. We
shouldn't throw rubbish and spit here and there. When there is some waste paper on the ground, pick
it up. We shouldn't smoke in public places, either, such as in the street, in the park or on the square.
Besides, we must protect trees and flowers. And we must take some steps to stop people from polluting
our river. If everyone tries his best to do something useful for our city, our city will become much more
beautiful.
That's all. Thank you.
