What is a public service announcement to protect birds?

As follows:

1. I advise you not to kill the bird on the branch. The son is in the nest looking for his mother to return.

2. Please protect birds for the sake of their sweet chirping tomorrow.

3. The blue sky can only be alive if it is accompanied by birds. Don’t let the sky become lonely.

4. Listen to the melody in the forest and cherish the notes in the sky - loving birds starts from the heart.

5. Give birds a sky where they can fly freely, and don’t let the lonely shengxiao blow through the lonely jungle.

6. Under the same blue sky, people and birds are at home.

7. We only have one earth. Under a blue sky, let us take new actions to protect and purify our earth.
