Now everyone advocates protecting the earth and our home, so let's take action to protect the earth and save natural resources with our wisdom and hands. The following are my suggestions. The first point: save paper.
1. Bind the useless paper in the old exercise book and make a draft.
2. Save paper and fill up the draft paper instead of throwing it away after writing a few words.
3. Try to save paper, whether it is toilet paper or napkin. If you can replace it with a handkerchief, use it instead.
4. Practice writing brush and painting Chinese painting on waste newspapers.
