Paper was first invented by China Cai Lun in A.D. 105. He made it a kind of wood.

Today, newspapers are still far from trees. We use three sheets of paper every day. We must use four sheets of paper now, because it has grown for about1100,000 years.

How can we have six sheets of paper? We can use 7 on both sides of each piece of paper. We can reuse envelopes. We can choose drinks instead of 8 cartons. We can use plastic cups and plates instead of paper. We can also use handkerchiefs instead of tissues. We can use less paper shopping bags, and we can reuse these paper bags.

It's difficult, please adopt it.
