According to a recent from the UN,the world's population continues to grow.It could reach 8.9 billion in the year 2025.
But during the past 10 years or so,a large rapid drop in the world's rate has taken place.Families generally are smaller now than they were a few years ago.It is happening in both developing and developed countries.
China has already have a negative groth rate.Experts said that these countries would not have enough workers in the future.And the people who are working could face much higher taxes to support the growing retiees.

根据一份最近的来自联合国(报道/调查,这里好像少一个词吧),世界人口继续增长.这个数字可能在2025年达到8,900,000,000.
但是在过去的10年左右的时间里,世界人口增长率还是有了大幅的迅速下降.现在的通常家庭都变得比几年前更小.这种现象不仅出现在发达国家,也出现在发展中国家.中国已经有了一个负的人口增长率.专家说这些国家将来会没有足够的劳动者.而那些劳动者也要面对高得多的税收,以次来支持不断增长的养老行业.
