The first thing I will do is from now on, I will do training everyday to keep health, and try to eat less fried foods and more fruits. The second thing i will do is from now on, I will talk and stay more time with my family to live in happiness and peaceful. The last thing I will do from now on is, work hard, study hard, and get success everyday.
For the country with high prevalence of HIV/AIDS, we can offer the pre-pregnancy check to the pregnant women, and change their living condition by offering their job or donate the money.
For the children born into poverty, the education of children is very important, so we must give the children the chance to study, this is the most important point. And we can also improve the living condition of the children, because they are building up their body and need lots of nutrition. The government should let go some law to protect the children, too.
For the women who born into inequality, the most important point is to change people’s mind of the equality between male and female. We are all born equality. We can also form more feminist organizations in order to let the women who are suffering the inequality have a barrier to protect themselves. The education for the young girls is a big problem. We should protect the right of women of learning. Once they have the knowledge, they would know how to protect themselves and stay away from the poverty.
2: from the data, we know that the dependency ratio is 38.82, I think it’s a bit low because it is lower than 40%, so that’s mean we have more workers than dependents.
3: in the year of 2017 of China, there are more births than the deaths, but the natural increase isn’t high. And the males in China are much more than the females. China has entered the stage 4, that is low birth rates, low death rates and low natural increase. But because of the large cardinal number, the population is still a big problem of China.
4: In the year of 2017 of China, the workers(14~64) is more than the dependents(0~14 and 65~), but the next few year, when the workers become the dependents, we seem to have fewer labors, the dependency ratio will increase so China will get into a little trouble of insufficient labor and aging population. Now China has let go of the two-child policy, it is helpful to reduce the stress from these two problems. The government can also let go of immigration policy to have more talents to work for China.
1: 70/1.09=64, that’s mean 64 years later our population will be overflow. This is concern because we, human being are running out all kinds of sources like oil, coals, nat gas and so on. Some day we will use them all and the Earth will be in a disaster.
2: With reference to the demographic transition model, we can see in the late human civilization, the birth rates will equal or very close to the death rates. That tell us the births in a year will roughly equal to the deaths in a year. So the population will be at a constant value, this is a and the only possible and peaceful to control the population.
3: Now the world is in the third stage, high birth rates, low death rates and the increasing population. After that, we will enter the fourth one, low BR, low DR and constant population. IIf the birth rates is lower than the death rates, we will enter the fifth stage. the population will decrease, and someday the birth rates will increase over the death rates again to gain more labors. So it’s possible to go backwards in stages.
4: The main point is concern about the overpopulation is a red herring; consumption’s the problem and the overpopulation is still a problem. The two authors both share the problem of overpopulation. I like the second article more, because it tells us the problem by telling us about the food and sources. No matter how much the population is, if the food and sourceshave been run out, the Earth is over. The reason I don’t like the first one is it only tell us the peak of population, and how many people can live in the Earth. That’s not reality. It’s roughly.
