There is a picture next to the reconstruction of the home. There are many stumps cut down in the foreground. In the close shot, there are two birds standing on the stump and whispering.

The bird's nest built between branches is not afraid of wind and rain, but also has the function of hiding eggs and protecting them. Without branches, the stump is completely exposed, which is very important for the survival and reproduction of birds. Only the dead branches on the edge of the cliff can be safe.

Afforestation gives birds a safe and stable home.

The biological chain is finally related to human beings.
