It has been estimated that a thousand years ago there were less than 400 million people on earth. Today, however, the world＇s population has amounted to 5,000 million. What is worse, it keeps growing at a surprising speed. If this trend continues, the world＇s population will shoot up to 7,000 million by the year 2000. This is what we call population explosion.
The rapid development of science and technology is the main cause of population explosion. We can see that the population has been growing at a tremendous speed since the Industrial and Agriculture Revolution in 1650, which raised the people＇s standard of living, and the emergence of modern medicine in 1550, which lowered the people＇s death rate.
Population explosion will result in a lot of such problems as food shortage, housing shortage and unemployment. It is time that we acted quickly to carry out the policy of birth control otherwise, man＇s survival on the earth will be threatened.
Many countries will experience aging populations in the next century because of declining birth and mortality rates. China will soon join their ranks. According to statistics, the aging of Chinas population will approach its peak by the middle of the next century,with the percentage of the people aged beyond 60 making up 27.4 percent of the total. That means one out of every four people will be elderly.
As for the issue of aging, its situation has been growing increasingly severe in spite of the fact most people are still ignorant of the problems it brings about. Firstly, with families becoming smaller and living , it is even graver for families to care for aged members adequately. Secondly, aging causes a relative decline in working force in that fewer people have to support the increasing aged people. Consequently, the productivity of the whole society is affected to some extent. Thirdly and most importantly,the aging of population in China resulted from the successful implementation of family planning has not been synchronized with national economic progress.
The rapidity of the populations aging has made it more urgent for the adoption of countermeasures. No doubt they key is to build a solid economic foundation. Meanwhile, importance shall be attached to overall changing the backward situation in social security,welfare and service.
Whats more, family care and community services shall also be encouraged.
