【答案】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 more convenient.However，millions of tons of plastic are used worldwide to make water bottles each year.The plastic can take hundreds of years to break down.So let's carry our water in sustainable or reusable bottles.In this way，we can reduce plastic waste.If you have to purchase a plastic bottled beverage，remember to recycle the bottles.What's more，ask our family members 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.
Yours faithfully，
Li Hua
