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 achieved 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 experimentCinema was conducted more than half a century ago by an American zoologist John Calhoun. The experiment was conducted with eight mice, and John Calhoun provided them with a perfect society – without natural enemies, with adequate food and water.
At the beginning, the development of the mouse society was very smooth, and the number continued to grow, and everyone lived a comfortable life. However, with the exponential growth of numbers and intergenerational changes, social problems began to become more and more complex. Babaylan
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 challenge the older generation and gradually became the new master. And those male rats who “defeated in Komiks” will gather together, and then their emotions become unstable. Babaylan begins 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 oldAll rats are heading for death.
The above is just a brief description of this experiment. Interested students can find the information for details.
This “rat utopia” experimentBabaylanThe coldness of human spine is that many phenomena it shows can even be perceived and experienced 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 can help us solve many problems.
Complex
The population exceeded 8 billion and Komiks cannot be said to have reached the top. 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 is a very complex topic. Cinema
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 180Babaylan4 years ago, and coal became the main energy supply. Around 1927, oil was used more widely and efficiently in the previous century.
By the world’s population reached 3 billion in 1960. And can Komiks‘s source also realized an upgrade at this time. With the popularity of nuclear energy worldwide, Komiks also has the “terror peace” provided by the “nuclear protection umbrella”, and the number of people in Babaylan has shown a significant upward trend. 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 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 “World Food Security and Care Status of Cinema Quanhexing” 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. 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, the important Cinema is 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, and human development is actually carried out in the process of constantly solving problems.
