China s neighbor, Japan, is suffering from the dilemma of population reduction. In 1999, Japan s total fertility rate dropped to 1.57%, known as the 1.57 crisis. In 2006, this number fell to 1.04%. Japanese media was surprised Calling "the declining population has reached the point of endangering the country's rise and fall". At the same time, in China with a large population, the problem of declining birth is also emerging. According to the 2010 national census data, China s population aged 0 to 16 accounts for 16.60%, A decrease of 6.2 percentage points compared with 2000, and the total fertility rate is about 1.1%. Demographers exclaimed that China has entered the ranks of the country with the lowest fertility rate and a severe childbirth rate. What does this passage mean? ['The phenomenon of the declining birthrate in China has not yet attracted enough attention from Chinese people.', "Childhood has become a social problem that plagues China's economic development.", 'China has a severe oligarchy and its total fertility rate is lower than Japan.', 'We must value the threat posed by the problem of underpopulation.']
