Whether in terms of their right to exist or their value to the ecosystem, an elephant and an ant are equal. From an evolutionary perspective, every wild species alive on Earth today is a repository of genes which have passed the test of natural selection. Only if "genetic diversity" is maintained can these genes come into play to respond to sudden changes in the environment.
一隻大象或一隻螞蟻，不僅在生存權利、生態上的價值都是一樣的，由演化角度來看，今天地球上的每個野生物種身上都保留了成功演化的基因，只有維持「基因歧異度」，才能隨時發揮功能，克服突如其來的環境危機。
