We can learn from past experience, and see that we have a tendency to over-exploit resources and to display a "locust swarm" type of behavior. As a result, when something gets well-known and becomes the object of "concern" of many people, the ending of the story can be tragic. Just like the stock market.
那就是證諸以往的經驗，我們常對「資源」過度使用，加上一窩蜂的現象，所以凡是正當紅、飽受大家「關愛」的事物，「下場」總是不太妙，股市是如此，紅龍魚也是這樣。
