When the Natives Meet the New-comers: This chance exists because the native animals have already lived with each other for tens of thousands of years, resulting in an ecological balance wherein things go along happily and pretty much unchanged. Hence, the natives are no match for tough recent arrivals eager to establish a place for themselves.
當本土動物遇上外來種由於本土動物彼此已相處成千上萬年，早已互相適應，生態維持在一個衡定狀態，日子過得樂天知命，頗為自在，因此往往個性馴良，不是初來乍到、急於安身立命、表現強勢的外來種對手。
