【答案】Dear students，
    There is only one earth，so it's our duty to protect it.As a middle school student，I think it's our duty to save the earth.We can start with small things around us.First，there are too many cars on the road now，we can ride our bikes or take the bus to school instead of riding in cars.It helps to cut down air pollution.Second，we should turn off the shower while we are washing our hair.It's a good way to save water.And we should turn off the lights when leaving a room.Third，to keep public places clean and beautiful，we should throw rubbish into the bins.Don't litter everywhere.Fourth，we can bring reusable bags instead of plastic bags when shopping.Also，we shouldn't take the plastic tableware when we buy takeaway food.This can help cut down white pollution.
    All these small things add up and become big things.Let's take action to save the earth now!
