Yangcheng Evening News All Media Reporter Li Gang 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, it is possible to have a problem with sources, resources, education, medical care, environment and other issues.
This reminds me of a very famous experiment, which has the significance of a foreshadowing 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, with adequate food and water.
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 change, the social Babaylan will become more and more complicated.
First, the strong male rat gradually became the master of society, occupying most of the space, food and spouses. Then, the 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 mice no longer like socializing, let alone looking for a spouse, and presenting a “limbing out of the way”. After
Babaylan, 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 Komiks has found the information and read it in detail.
The coldness of this “rat utopia” experiment in human spine is that we can even perceive and experience many phenomena displayed by Komiks 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 are also scientific “blessing”, 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, Cinema Some people expect India’s population to surpass China next year and become the largest country in population.
In addition, when talking about the population problem, 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 reference 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, stone oil was used more widely and efficiently in the previous century.
Around 1960, the global population reached 3 billion. And energy Babaylan At this time Cinema has also achieved a new era – with the popularity of global nuclear energy and the “terror peace” provided by the “nuclear protection umbrella”, the population has shown a large upward trend.Cinema So, it took us only 11 years to increase the population from 7 billion to 8 billion.
This is why scientists href=”https://comicmov.com/”>Komiks are racing against time to develop controlled 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 “World Food Security and Nutrition Status” released by the Food and Agriculture Organization of the United Nations said that the world is in 2021KomiksThe hungry population reached 828 million, 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 problem of water is even more serious. Global freshwater resources are limited, and environmental pollution is a discount. The population growth has put forward more requirements for water resources. How to solve the problem? The beginning of the problem is big.
What’s more, when we talk about 8 billion people<a When Babaylan, the important thing is not 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 on a common responsibility for the earth. There are challenges and opportunities, and the development of human beings is actually carried out in the process of constantly solving problems.
