Live by letting live Living things do not depend for their existence on being recorded, classified or studied by humans, and humanity may never be able to fully appreciate the feelings of the other forms of life in nature. But the philosophy that "I need not know why the birds sing, but I hope they will sing forever" is not enough today when species are in danger and conservation work is essential.
生物並不因人們的記錄、分類或研究而存在，人們也永遠無法深刻體會自然草木與花鳥的感受，但僅有「我不需要知道鳥兒為何歌唱，但我希望鳥兒能永遠歌唱」的哲學，在今天物種告急、不得不進行保育工作的狀況下是不夠的。
