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.
