Students, when we open the window, we can see a bare land, and we can't see any green. Get up in the morning to breathe the air, there is no freshness, dust is sucked into the nose, which makes us cough. How will we feel at this time?

Now the forest is disappearing, and so is the green. Protecting trees and forests is a top priority. As children of the earth, as citizens, we should start from ourselves.

Every Arbor Day, we not only plant trees ourselves, but also call on people around us to plant trees together. Do you know the benefits of planting trees? I tell you, there are too few trees where the mudslide happened. If there are more trees, the roots will go deep into the ground and connect with the roots of each tree, so that the soil will be fixed and there will be no mudslides. We should stand up and remind you, do you know the ecological value of a tree? Professor Des of Calcutta Agricultural University in India calculated the ecological value of a tree: a 50-year-old tree produces about $365,438+$0,200 of oxygen, absorbs toxic gases to stop the atmosphere, and pollutes about $62,500; Increase the value of soil fertility by about $365,438+$0,200; Resulting in a protein worth $2,500. Excluding the value of drugs, fruits and wood, the total value is about $ 196000. Yes! How important a tree is!

We should do our duty and contribute to the creation of forests. First of all, we should not destroy trees. Every Arbor Day, we plant a responsibility and a contribution. Let's contribute to the creation of new forests.

In our new home, it is not enough to rely on one person. We should build everyone's strength together, so that we can have a green and beautiful home.

Let's make contributions to creating forests and protecting trees, and jointly build a beautiful new home!
