A doomsday clock counts down the seconds until extinction.
國家消亡的倒計(jì)時(shí)已經(jīng)開始。

Over time, low, unchanging fertility rates (without additional immigration) could mean actual extinction for an entire country.
隨著時(shí)間流逝，不變的低生育率（又沒有移民流入）將意味著日本整個(gè)國家的消失。

In the short term, that could mean losing 34% of the country's population by 2100.
短期來看，這意味著日本人口將在2100年前減少34%。

Taking a longer view, Japanese researchers recently pinned down the expected date of extinction with a doomsday clock. The date, according to the latest fertility rates, is August 12, 3776.
長遠(yuǎn)來看，日本研究人員已經(jīng)用末日鐘算出了日本人滅絕的時(shí)間。根據(jù)最新的生育率來估算，日本滅絕的日期將是3776年8月12日。
