I am a pessimistic person, so after hearing that the global population exceeded 8 billion on November 15, I had a lot of worries.
Experiment
On the one hand, population growth is a good thing, which shows that human civilization has achieved great achievements in building a society suitable for survival and development. On the other hand, energy, resources, education, medical care, environment and other issues will face challenges.
This reminds me of a very famous experiment, which is quite foreshadow and warning.
The experiment was conducted more than half a century ago by an American zoologist John Calhoun. The experiment was conducted with eight mice. John Calhoun provided them with a perfect society – without natural enemies, and 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. Komiks 1960 witch cloth draw However, with the exponential growth of the number and the intergenerational change, social problems began to become more and more 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 male rats 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 new generation of Babaylan 1990 cloth drawMouse no longer likes socializingCinema 1950 witch cloth draw, let alone find a spouse, and appear to be “lying flat”. After that, the mouse club Cinema 1950 witch cloth draw will start to collapse, the birth rate is seriously lower than the mortality rate, and eventually all rats will die.
The above is just the Komiks 1960 witch cloth draw briefly describes the Cinema 1950 witch cloth draw experiment. Interested students can find the information themselves and take a look at it in detail.
What makes this “rat utopia” experiment cool down on human spine is that it shows 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 rat society, and we also have the “blessing” of science, laws and social rules, and government regulation, all of which are Cinema 1950 witch cloth draw 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. Komiks 1960 witch cloth drawFor 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, the vision is obviously narrow. The number of population is the result of a comprehensive factor. 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, Babaylan 1990 cloth draw reached 2 billion, and then it has accelerated its growth.
It is worth noting that Babaylan 1990 cloth draw is that the industrial revolution was taking place around 1804, and coal became the main energy supplyBabaylan 1990 cloth draw. Around 1927, oil was used more widely and efficiently in the previous century.
Around 1960, the global population reached 3 billion. Energy has also achieved an upgrade at this time – with the popularity of nuclear energy worldwide 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 Komiks 1960 witch cloth draw, and the population grew from 7 billion to 8 billion.
This is why scientists are racing against time to develop controlled nuclear fusion technology, because this new energy form is an important and necessary key to solving the problem of sustainable development of human society at present.
Let’s look at the two necessities of food and water that maintain human survival. The Food and Agriculture Organization of the United Nations said in the “State of World Food Security and Nutrition” released by the FAO of the United Nations that in 2021, the number of hungry people around the world reached 828 million, and there were 3.1 billion.People cannot afford a healthy diet. In comparison, it is ridiculous that the global annual grain output is enough to feed 15 billion people. Such a distribution mechanism Cinema 1950 witch cloth draw problem needs to be solved urgently.
The water problem is even more serious. The global freshwater resources are limited, and the overlapping environmental pollution will require a discount. 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 moment when human beings think about taking common responsibility for the earth. There are challenges and opportunities, and human development is actually carried out in the process of constantly solving problems.
