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, which shows that human civilization has made great achievements in building a society suitable for survival and development. On the other hand, issues such as energy, resources, education, medical care, and the environment will face challenges.
This reminds me of a very famous experiment, which is quite foreshadow and warning. The experiment was conducted by an American zoologist about half a century ago by Babaylan, who was an eight rat, and John Calhoun provided them with a perfect society—without Cinema, with sufficient 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 the number and the intergenerational replacement, social issues are becoming increasingly complex.
First, the strong male rat gradually became the master of society, occupying most of the space, food and spouses. Then, a new generation of ambitious heroes began to constantly challenge the older generation and gradually became the new master. The male rats who were “defeated” would gather together, and then their emotions became unstable and they began to attack each other.
Continue to develop, the newborn rats no longer like social interactions, let alone find a spouse, Komiks, and appear to be a “lying flat” state. Komiks
After, the rat society began to collapse, the birth rate was seriously lower than the mortality rate, and eventually all rats died.
The above is just a brief description of this experiment. Interested students can find the information themselves and take a look at it in detail.
The Cinema experiment makes the human spine cooler because we can even perceive and experience many phenomena that we can even perceive and experience in our current social life.
Of course, it is obviously not scientific to judge the direction of human society based on this. Because human society is much more advanced and complex than mouse society, and we also have the “blessing” of science, laws and social rules, and government regulation, thisKomiks everything 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 it is a very complex topic.
A very interesting indicator is the energy form. You see, in 1804, the global population was 1 billion, and in 1927 it reached 2 billion, and then it accelerated its growth.
It is worth noting that Cinema was in the industrial revolution around 1804, and coal became the main energy supply. Around 1927, oil was used more widely and efficiently in the previous century.
Around 1960, the global population reached3 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. Babaylan So it took us only 11 years to grow from 7 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 healthy diets. Compared with this, it is ridiculous that the annual global grain production is enough to feed 15 billion people. Such a distribution mechanism problem needs to be solved urgently.
The water problem is even more serious. The global freshwater resources are limited, and environmental pollution will 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 the population of 8 billion, the important Komiks are no longer just quantity, 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 moment when human thinking takes common responsibility for the earth. There are challenges and opportunities. Human development is actually carried out in the process of constantly solving problems. Cinema
