Every 14 days a language dies. By 2100, more than half of the more than 7,000 languages spoken on earth will likely disappear, taking with them a wealth of knowledge about history, culture, the natural environment, and how the human brain works.
Language defines a culture. Words that describe a particular cultural practice or idea rarely translate precisely into another language. Many endangered languages have rich oral cultures with stories, songs, and histories passed on to younger generations, hut no written forms. With the disappearance, an entire culture is lost.
Much of what humans know about nature is expressed only in oral languages. Indigenous (土著) groups that have interacted closely with the natural world for thousands of years often have deep insights into local lands, plants, animals, and ecosystems (生态环境). Studying indigenous languages therefore benefits environmental understanding.
Studying various languages also increases our understanding o
A. History and wealth of human beings.
B. Much of the knowledge of human beings.
C. The way the human brain works.
D. The natural environment of the world.
