Proposal

 

Dear schoolmates,

Now pollution is becoming more and more serious. It’s our duty to protect the environment. The Students’ Union calls on everyone to follow the three‑R principles.

 

First, reduce waste. Try to cut down the use of single‑use products. Second, reuse daily things like bottles and bags as much as possible. Third, learn to sort rubbish and recycle paper, plastic and metal.

 

Small actions can make a big difference. Let’s start with small things around us and work together for our only one Earth.
