My idea to change the world is that every person aged 21 to 41 in the world would be 1）mandated to travel to a foreign place. The place of travel would be chosen at random by computer， and the travellers at his or her destination will be tasked with teaching the person the local 2）ritual， a bit of wisdom or a traditional healing method. Now， in South Africa， for example， there are a number of traditional 3）healers， and they hold a vast amount of knowledge， and， while this knowledge is 4）sacred and protected， a lot of it would be useful to those who usually go the 5）biomedical route. This idea would not only broaden the persons mind—the traveling idea， that is， but traditional knowledge would be preserved in a living manner. So I think overall that this is a…is a good idea because， by travelling， people would broaden their minds， they would preserve， they would contribute to the preservation of biocultural diversity， for example in 6）Zanzibar， a number of herbs and spices， for example， are used to basically help the person to 7）rejuvenate their body on a daily basis.

我改變世界的想法是全世界年齡段在21至41歲的人都要去別國旅游。旅游的地方由電腦隨機選擇，這些人在旅游地的任務是（回來后）教授人們一些當地的禮制、智慧或者一種傳統(tǒng)的療法。例如，現在在南非，有很多傳統(tǒng)的醫(yī)士，他們掌握大量的知識。盡管這些知識神圣而受保護，但是它們對與那些靠生化療法治病的人很有幫助。這一旅游的想法不僅能拓寬人們的視野，而且還能在生活中將傳統(tǒng)知識保存下來。所以我認為總的來說這是一個好的想法，因為通過旅游人們可以增長見識，能夠對保護生態(tài)文化的多樣性作出貢獻。例如，在桑給巴爾，許多草藥和調料能夠在日常生活中幫助人們復原身體。
