Writing a persuasive letter
1 Read the letter and answer the questions.
Dear Friends,
We are writing this letter to call on everyone to take part in the Clear Your Plate campaign. It urges people to save food by not wasting anything on the dining table. You may not know over 30% of the world’s food is wasted, while many people in poor areas do not have enough to eat. In order to save food, we propose:
1 Do not order more than you need in the school canteen.
2 Order less and take leftover food home when dining in restaurants.
3 Call on family members and friends to take part in the campaign.
Reducing daily food waste by just 5% could save millions of people from starvation. Let’s start doing what we can to make the world a greener, cleaner place!
With best wishes,
Class 8

Dear Friends,
We are writing this letter to raise your awareness of the need to protect our planet. You can help simply by participating in the No Bottled Water campaign.
People tend to think bottled water is cleaner and more convenient. However, they may not know that according to scientific research, millions of tons of plastic are used worldwide to make water bottles each year. The plastic can take hundreds of years to break down.
Writing a persuasive letter
If you are worried about the effects of bottled water on the Earth, we would like to suggest you take the following steps.
