為什么要保護物種和語種?首先在于權利。每一物種都有在地球上生存的權利,每一個小民族都有使用祖先傳遞給他們的語言的權利,那幾乎是他們最重要的特征,其次,這種保護對其他物種,對其他人,對全人類都有好處,文化儲藏和積淀在語言中。人類文化的多樣性儲藏在其多樣的語種中。一個強健的生態系必然是多樣的,反過來這種多樣性又可以幫助它適應和安度環境的變遷,正如同一個愚鈍的村婦寧愿犧牲一點便利,也會拒絕將她的全部雞蛋放在一個籃子里。
Every species is entitled to earthly existence, so is every minority to their own language, the most important feature of what has been passed from their ancestors. Secondly, such protection of species and languages is favorable to all species including human beings. Cultures are embodied and conserved in languages, while cultural diversities are preserved in linguistic diversities. A sound ecosystem is bound to be diverse, which, in turn, facilitates its adaption to the changing environment. It is in very much the same way as a maladroit countrywoman, though a little inconvenient for her, would refuse to put all her eggs in one single basket.
