This all goes to show that organisms do not simply exist as pretty ornaments to enrich the natural world--every one of them interacts with others and has its part in maintaining the ecological balance. The disappearance of any single species affects all others--including mankind, who depends on natural resources for survival.
這些都說明每個生物的存在，不只是扮演豐富自然界的花瓶而已，而是彼此間相生相剋，維持著平衡，若一個物種減少，包括依賴自然資源維生的人類也會受到牽連。
