When I was very young ,the sky in my homet own was nice and beautiful, the sky was very blu e,and the air was fresh.
There were some birds singing ,and there w ere many trees in the fields. I often played with my friends in the open air.I liked it.
The rubbish is put here and there, it was bad for our health.So wo must do something to prote ct the environment.
If we make a contribution to protecting the e nvironment,the sky will become much more bea utiful.
