I am a pessimistic person, so after hearing that the global population exceeded 8 billion on November 15, I had a lot of worries.
Experience
Komiks 1960 witch cloth drawPopulation 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, energy Cinema 1950 witch cloth drawKomiks 1960 witch cloth draw, resources, education, medical care, environment and other topics 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 mouse society was very smooth, and the number continued to grow continuously, and everyone lived a comfortable life. However, with the exponential increase of the number and the generational 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 Komiks 1960 witch cloth draw is the new generation of ambitious Cinema 1950 witchcloth drawMale rats began to constantly challenge the older generation and gradually became the new master. And those “defeated” male rats would gather together Babaylan 1990 clothes draw, and then their emotions became unstable and they began to attack each other.
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 mortality rate, and eventually all the 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 place where this “mouse utopia” experiment makes the human spine cooler is that it shows many phenomena that we can even perceive and experience in the 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 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’s 1950 witch cloth draw next year, becoming the largest country in population.
In addition, when it comes to population issuesKomiks 1960 witch cloth drawBabaylan 1990 cloth draw, just talking about birth rate and mortality rate, then the field of vision is obviously narrow, Komiks 1960 witch cloth drThe number of aw population is a result of a comprehensive factor Babaylan 1990 cloth draw, and 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 the industrial revolution was taking place 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 reached 3 billion. At this time, energy has also achieved a new era—Komiks 1960 witch cloth draw—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 1990 cloth drawSo, it took us only 11 years to grow from 7 billion to 8 billion. This is why scientists are competing for points and developing controlled nuclear fusion technology in an anti-second manner, because this new energy form is an important and necessary key to solving the current sustainable development of human society.
Let’s look at Cinema 1950 witch cloth draw to see food and waterTwo essentials for maintaining human survival. 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 were unable to afford healthy diets. In comparison, it is ridiculous that the global annual grain output 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 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 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.
