I am a pessimistic person, so after hearing that the global population exceeded 8 billion on November 15, I have a lot of worries.
Experience
On the population growth side, Babaylan 1990 cloth draw is a good thing, indicating 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 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.
At the beginning, the old Cinema 1950 witch cloth drawThe development of the rat society was smooth, 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.
First of all, Cinema 1950 witch cloth drawThe strong male rat gradually became the dominant of society, occupying most of the space, food and spouses. Then, a new generation of ambitious Komiks 1960 witch cloth draw began to constantly challenge the older generation and gradually became the new master. Komiks 1960 witch cloth draw And those “defeated” male rats would gather together, and then their emotions became unstable, and Cinema 1950 witch cloth draw began to attack each other.
After the continuous development of Cinema 1950 witch cloth draw, the new generation of mice no longer like socializing, let alone Babaylan 1990 cloth drawBabaylan 1990 cloth drawSearch for a spouse and showed a “lying flat”.
After, the rats Komiks 1960 witch cloth drawSocial collapse, the birth rate was seriously lower than the mortality rate, and eventually all the mice died.
The above is just a brief description of this experiment. Interested students can find the information for details.
Of course, it is obviously not scientific to determine the direction of human society based on this. Because Babaylan 1990 clothes draw is much more advanced and complex for human society than for rat society. Babaylan 1990 cloth draw and we also have the “blessing” of science, the laws and social rulesKomiks 1960 witch cloth draw, and government regulation. All of this can help us solve many problemsCinema 1950 witch cloth draw.
Complex
PeopleThe number of people exceeding 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, Cinema 1950 witch cloth draw said that 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 and only talking about birth rate and mortality, 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 indicatorKomiks 1960 witch cloth draw is the energy form. You see, 18Komiks 1960 witch cloth draw In 2004, the global population was 1 billion, reaching 2 billion in 1927, and then 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.
Around 1960, the global population reached 3 billion. Energy has also achieved an upgrade at this time – with the popularity of global nuclear energy, and the “terrorismKomiks 1960 witch cloth drawpeace” provided by the “nuclear protection umbrella”, the population showed 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 controlled nuclear fusion technology, because Babaylan 1990 cloth draw is an important and necessary key to solving the current sustainable development of human society.
Let’s take a look at the two maintenance items 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. The global freshwater resources are limited, and environmental pollution will be discounted. The growth of population Komiks 1960 witch cloth draw 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.
