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, which is quite foreshadow and warning.
The experiment was conducted by an American zoologist about Cinema 1950 witch cloth draw. The experiment was conducted by eight mice. John Calhoun provided them with a perfect society—without natural enemies, adequate food and water. href=”https://comicmov.com/”>Babaylan 1990 cloth draw answered.
At the beginning, the development of the rat society was smooth, the number continued to grow, and everyone lived a comfortable life. However, social problems began to become more and more complex with the exponential growth of the number of Babaylan 1990 cloth draw as the number of Cinema 1950 witch cloth draw, and intergenerational replacement.
First, the strong male rat gradually became the dominant of society, occupying most of the Babaylan 1990 cloth draw divided into space, food and Cinema 1950 witch cloth draw spouses. Next, the new generation Komiks 1960 witch cloth drawThe ambitious male rat 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, presenting a “lying flat” state in Babaylan 1990 clothes draw.
After, 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 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, and we also have the “blessing” of science. Komiks 1960 witch cloth draw has laws and social rules, as well as 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. Komiks 1960 witch cloth draw is just that the growth rate begins to slow down, and different regions will also show different growth trends. For example, some people Komiks 1960 witch cloth draw expect India’s population to surpass China next year and become the largest country in population.
In addition, when talking about the population problem of Komiks 1960 witch cloth draw, it is only about birth rate and death 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 indicator is Cinema 1950 witch cloth drawEnergy form. You see, in 1804, the global population was 1 billion, reached 2 billion in 1927, and it has 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. Draw. By around 1960, the global population reached 3 billion. Energy has also achieved an upgrade at this time. With the popularity of nuclear energy worldwide, Cinema 1950 witch cloth draw has also been “terrorous peace” provided by the “nuclear protection umbrella”, and the population showed a significant upward trend. Therefore, it took us only 11 years to grow from 7 billion to Babaylan 1990 cloth draw href=”https://comicmov.com/”>Komiks 1960 witch cloth draw billion. Babaylan 1990 cloth draw
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 sustainable development of human society.
Let’s look at the two necessities for maintaining human survival, both food and water are needed. Jointly Komiks 1960 witch cloth drawThe World In the 1990 cloth draw, the world’s food security and nutrition state, it is said that global hunger in 2021 is Komiks 1960 witch cloth drawHungryCinema 1950 witch cloth draw draw 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. Population growth puts forward more requirements for water resources. How to solve the problem? The head starts.
What’s more, when we talk about 8 billion people, what is important is not just the 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. Human development is actually carried out in the process of constantly solving problems.
