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 in Komiks 1960 witch cloth draw, 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 Babaylan 1990 cloth drawLhoun provided them with a perfect society – without natural enemies, with adequate food and water supply. Cinema 1950 witch cloth draw
At the beginning, the development of the mouse society was very smooth, and the number of Cinema 1950 witch cloth draw was growing continuously, and everyone lived a comfortable life. However, as the exponential expression of the Cinema 1950 witch cloth draw increases, and intergenerational replacement, social problems begin to become more and more complex.
Cinema 1950 witch cloth drawFirst, the strong male rat gradually became the master of society and accounted for the”https://comicmov.com/”>Babaylan 1990 cloth draw based on most of the space, food and spouses. Then, a new generation of ambitious male rats began to constantly challenge the older generation, and Komiks 1960 witch cloth draw gradually became the new master. The male rats who were “defeated” would gather together, and then their emotions became unstable and began to attack each other.
Continue to develop, the new generation of miceBabaylan 1990 clothes draw no longer likes socializing, let alone find a spouse, and present a “lying flat” state. After that, the rat society began to collapse, and the birth rate was seriously low. Komiks 1960 witch cloth draw 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.
What makes this “rat utopia” experiment cool down the 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 mouse society, we also have the scientific “Cinema 1950 witch cloth draw”, which has laws and social rules, and government regulation, all of which can help us solve many problems.
Complex
The population exceeds 8 billion, which cannot be said to have reached its peak. Judging from the population structure of Komiks 1960 witch cloth draw population structureCinema 1950 witch cloth draw 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, 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 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.
Babaylan 1990 cloth draw By Cinema 1950 witch cloth drawAround 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 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 current problem of sustainable development of human society.
Let’s Babaylan 1990 cloth draw to see the two maintenance of food and waterA necessity for 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 are 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. Global freshwater resources are limited to Komiks 1960 witch cloth draw, and if you add environmental pollution, you will have to give 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 we want 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 common responsibility for the earth. There are challenges and opportunities, and human development is actually carried out in the process of constantly solving problems.
