Homework Homework
Dear________,
These days I just felt very frustrated, for I cannot put up with pollution. Sometimes I felt that individuals can have little effect on such huge environmental problems. However, I still thought people should advocate improvements in the way we use today.
So I wrote a letter to the Earth Care to ask for suggestions. They told me that many people who have a commitment like me, but they do not believe they have the power to do anything to improve the environment. However, they said That's not true. Because, together, individuals can make a difference. We do not have to put up with pollution.
According to the suggestions that they gave me, I made a poster, and now I'd like to share it with you.
