Digital ID for Trees
In Leshan, Sichuan, newly planted trees have a special digital ID—a QR code. Scan it with a phone, and you can see information about the tree. Without such protection, trees could be cut down illegally, and the ecosystem would lose its balance.
How does it work? First, the grower uses a phone app to enter the tree's type, size and origin. The app then creates a QR code in just one minute. When sold, the buyer scans the code and the information appears. No surprise, this smart system saves time and reduces waste.
The digital ID helps growers a lot. Before, they had to fill out paper forms for every young tree. Now, they create an electronic tag in one minute. As a result, fewer trees are cut
down for paper, and the rapid development of technology works with nature, not against it.
The ID also helps buyers. They can scan the code to check if the trees are real and healthy. This stops fake trees. We need to think more about how we get along with nature, and this invention is a good example.
For the government, it tracks where trees come from and go. It makes sure trees are grown and sold properly. Throughout history, humans have left many marks on the earth—some harmful, some helpful. This digital ID leaves a helpful mark.
By the end of 2026, all new young trees in Leshan will have such an ID.

A.To explain how to plant trees in Leshan.
B.To argue that technology is usually harmful to the environment.
C.To introduce a digital ID system for trees and show how it helps protect nature.
