Endless road to extinction | chirping

On the big stage of life on Earth, human beings are just a drop in the ocean. However, today, when humans spend 3.5 billion yuan to build a steel "bird's nest", the birds no longer have a towering tree to settle down in; When human beings spend 1 billion yuan to create a blue "water cube", the fish no longer have a clear river that can reproduce; While the human population continues to exceed 6.5 billion, our fellow humans are on an endless path to extinction!
