There're 7，000 documented languages currently spoken across the world，but half of them could be endangered，according to a new study.It's predicted that 1，500 known languages may no longer be spoken by the end of this century.
    Researchers from The Australian National University analyzed thousands of languages and highlighted a link between higher levels of schooling and language loss，as regionally leading languages taught in class often overshadow native tongues.Additionally，the density of roads in an area is also to blame.
    "We found that the more roads there are，connecting country to city，and villages to towns，the higher the risk of languages being endangered，" said Professor Lindell Bronham，co-author of the study.
    The study，published in Nature，Ecology and Evolution，estimates the equivalent （等量，對應物） of one language is currently lost within every three-month period.But levels of language loss could actually triple（三倍）in the next 40 years，with at least one language per month disappearing unless measures are taken.
    "When a language is lost，we lose so much of our human cultural diversity，" said Professor Bromham. "Fortunately，many of the languages predicted to be lost this century still have fluent speakers，so there's still the chance to invest in supporting communities to boost native languages."
    While past studies have blamed the digital area for causing the language loss—by focusing attention on a few major languages at the expense of smaller ones—today's tech-focused world could hold a solution.
    There're plenty of Internet sites and apps to help new speakers learn languages like Spanish，English and Chinese，but these now extend to specialist apps designed to teach endangered languages or help preserve them.Ma!Iwaidja，for example，is an app that enables those working with speakers of the Iwaidja language to record words，phrases and translations.Another initiative is the Rosetta Project，a global cooperation of language specialists and native speakers working to build an open-access digital library of human languages.
    The UNESCO International Decade of Indigenous Languages （IDIL2022-2032），which begins this year，also aims to engage the global community with the critical issue of language loss.As part of its Global Action Plan，it is creating a network of international stakeholders focused on protecting the rights of indigenous people to restore and preserve their languages.
