Read the letter and answer the questions.
1 What is the purpose of the letter

Sample
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.
If you are worried about the effects of bottled water on the Earth, we would like to suggest you take the following steps.
Sample
1 Carry your water in a sustainable, reusable bottle. In this way, you don’t need to buy bottled water.
2 If you have to purchase a plastic bottled beverage, recycle the bottle after use.
3 Call on your family members and friends to take part in this campaign.
Everyone is responsible for making our planet cleaner and better by doing what we can. Let’s start NOW.
With best wishes,
Class 11
