Shi Lang and Amelia came to the bird enclosure holding hands with each other. The girl was full of smiles as she stood in front of a big cage, watching colorful small birds flying around. She said, "You know Lang, once there was a time when these little ones almost went extinct. I wonder, how our predecessors became so blind that they could not see the consequences of their actions?" 

Shi Lang did not say anything for a few minutes, as his gaze lingered upon the birds flying and tweeting inside the cage. He said, "I have read in a lot of books that humans tried to learn from the creatures to assimilate better with the nature around. However, before they could do that, they were almost on the verge of collapse. I guess the ancient saying of the destruction of the old is necessary for the creation of new, is correct and true. The good thing is that humanity corrected its ways."
