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, indicating that humans have 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 meaningful 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.
In the beginning, the mouseBabaylan 1990 cloth drawSocial development 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, 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 Cinema 1950 witch clothes draw is that a new generation of ambitious male rats have begun to constantly challenge the older generation and gradually become the new master. And those “defeated” male rats would gather together, and then their emotions became unstable. Komiks 1960 witch clothes draw fixed on each other and began to attack each other.
Continue to develop, the new generation of mice no longer like socializing, let alone looking for a spouse, Komiks 1960 witch cloth draw presents a “lying flat” state.
After, the rat society began to collapse, the birth rate was seriously lower than the mortality rate, and eventually all rats died.
以上只是简述了这个实验,有兴趣的同学们可以自己查找资料详细看看。 The experiment of this “rat utopiaBabaylan 1990 cloth draw” makes the back of the human spine cooler in 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. Cinema 1950 witch cloth drawBecause human society Babaylan 1990 clothes draw will be much more advanced and complex than mouse society, and we have scientific “blessing” and law, social rules, and government regulation. All of this isCinema 1950 witch cloth draw/”>Cinema 1950 witch cloth draw can help us solve many problems.
Complexity
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 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, and the population is a comprehensive Babaylan 1990 clothes The result of draw combined with factors is a very complex topic. An interesting indicator is the energy form. You see, in 1804, the global population was 1 billion, reached 2 billion in 1927, and has accelerated its growth since then.
It is worth noting that Babaylan 1990 cloth drawAround 1804, Cinema 1950 witch cloth drawIndustrial revolution was underway, and coal became the main energy supply. Around 1927, oil was profited more widely and efficiently in the previous century. 1960 witch cloth draw. Komiks 1960 witch cloth draw
Around 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. Therefore, it took us only 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 factor in solving the problem of sustainable development of human society at present. The cloth draw key is located.
Let’s take a look at the two maintenance items of food Babaylan 1990 cloth draw 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. Cinema 1950 witch cloth drawIn comparison, it is ridiculous that the global annual grain production is enough to feed 15 billion people. Such a distribution mechanism problem needs to be solved urgently.
水的问题更为严重。 The global freshwater resources are limited, and the superimposed environmental pollution will have to be discounted again. 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, and human development is actually carried out in the process of constantly solving problems.
