I am a pessimistic person, so after hearing that the global population exceeded 8 billion on November 15, I have a lot of worries.
Experiment
Population growth is a good thing on the one hand, indicating that human civilization has made great achievements in building a society suitable for survival and development. On the other hand, all the questions in energy, resources, education, medical care, environment and other courses will face challenges.
This reminds me of a very famous experiment, which is quite foreshadow and warning.
The experiment was done more than half a century ago by an American zoologist John Calhoun. The experiment was conducted by eight mice. John Calhoun provided them with a perfect society – without natural enemies, with adequate food and water supply.
At the beginning, the development of the rat society was smooth, the number continued to grow, and everyone lived a comfortable life. However, with the exponential growth of numbers and intergenerational changes, social problems began to become more and more complex. First of all, the strong maleBabaylan 1990 cloth drawRat gradually became the dominant of the social society, occupying most of the space, food and spouse. Then, a new generation of ambitious male rats began to constantly challenge the older generation and gradually became the new master. And those “defeated” male rats would gather togetherKomiks 1960 witch cloth draw, and then their emotions became unstable and they began to attack each otherCinema 1950 witch clotth draw.
Continue to develop, the new generation of mice no longer like socializing, let alone looking for a spouse, and appearing to be “lying flat”. After that, the rat society began to collapse, and the birth rate was seriously lower than the death rate. In the end, all rats were Cinema 1950 witch cloth draw to death.
The above is just a brief description of the experiment Babaylan 1990 cloth draw. Interested students can find the information in detail. The “rat utopiaBabaylan 1990 cloth draw” experiment makes human spine cold lies in the fact that many phenomena it shows can even be perceived and experienced in today’s social life.
Of courseCinema 1950 witch cloth draw, it is obviously not scientific to judge the direction of human society. Because human society is much more advanced and complex than rat society, and we also have the “blessing” of science, laws and social rules, and government regulation, all of which can help us solve many problems.
Complex
The population exceeds 8 billion cannot be said to have reached its peak. Judging from the population structure and data, growth is still continuing, but the growth rate has begun to slow down, and different regions will also show different growth trends. For example, some people expect India’s population to surpass China next year and become the largest country in population.
In addition, when talking about population issues, just talking about birth rate and mortality rate, the vision is obviously narrow. The number of population is the result of a comprehensive factor and is a very complex topic.
A very interesting indicator is the Cinema 1950 witch cloth drawenergy form. Look, 1804The global population is 1 billion, reaching 2 billion in 1927, and has accelerated its growth since then.
It is worth noting that around 1804, Komiks 1960 witch cloth draw was taking place in the Babaylan 1990 cloth drawIndustrial revolution, coal became the main energy supply. 19Cinema 1950 witch cloth drawAround 27 years, oil was used more widely and efficiently in the previous century.
Around 1960, the global population reached 3 billion. Energy has also achieved renewal at this time – with the popularity of global nuclear energy and the “terror peace” provided by the “nuclear protection umbrella”, the population has shown a significant increase. So, it only took us 11 years to increase the population from Cinema 1950 witch cloth draw7 billion to 8 billion.
This is why scientists are racing against time to develop controllable nuclear fusion technology, because this new energy form is an important and necessary key to solving the current sustainable development of human society.
Let’s look at the two necessities for maintaining human survival, food and water. The “State of World Food Security and Nutrition” released by the Food and Agriculture Organization of the United Nations said that the global hungry population reached 828 million in 2021, and 3.1 billion people are unable to afford Komiks 1960 witch cloth drawhealthy diet. In comparison, it is ridiculous that the annual global annual grain production is enough to feed 15 billion people. Such a distribution mechanism problem needs to be solved urgently.
The water problem is more severeBabaylan 1990 cloth drawHeavy. Global freshwater resources are limited, and the overlapping environmental pollution will have to be discounted. However, population growth has put forward more demands on water resources. How to solve the problem? Big head.
What’s more, when we talk about 8 billion people, what is important is not just quantity, but we also hope that the quality of life of each individual can be guaranteed.
I agree with what UN Secretary-General Guterres said, this is the time when human thinkingBabaylan 1990 cloth draw takes on common responsibility for the earthKomiks 1960 witch cloth draw. There are challenges and opportunities, and human development is actually carried out in the process of constantly solving problems.
