How many people can the earth really carry? How many billions of people are the limit?

How many people can the earth really carry? The answer to this question is not easy to say, but one thing is certain: the number of people on the planet today far exceeds the number of people it can carryIn recent years, the earth's environment has been damaged more and more rapidly, which is undoubtedly closely related to the excessive number of people, of course, the carrying capacity mentioned here does not mean that after exceeding this number, the earth can not operate normally, after exceeding this number, for the earth, its burden has increased greatly, and various self-repair functions have been greatly limited, according to the conclusion of relevant people, the current number of people on the earth has exceeded 70% of the earth's load, While the accuracy of this statement is debatable, it reflects the overpopulated nature of the planet. <>

Carrying capacity and limit are two different concepts, the carrying capacity of the earth may not be much compared to the limit, but if it is not for the extreme increase in the population of the earth, it is easy to accommodate the population of the earth, some people may askHow many people are the limits of the planet? The answer is 16 billion peopleAccording to the research and summary of many experts, they finally came up with the figure of 16 billion, although in terms of the current population, this number is still a little far from us, but this does not mean that human beings can increase the number of people unbridled, once the population limit is reached, then the disaster faced by mankind must be devastating. <>

Human beings live on the earth, and they are inseparable from these things all the time, which are water, food, habitable environment, and living conditions. The resources of the earth are limited, if human beings do not control the number of people, do not pursue the harmonious development of man and nature, but wantonly destroy the environment, and plunder the resources of the earth wirelessly, it seems that only the earth was injured in the beginning, and human beings have not been affected much, but in the near future, the earth will definitely double these punishments on human beings, and this means that human beings will face the greatest challenge and even extinction. <>

In short, the number of human beings has exceeded the capacity of the earthMany people may seem to think that there is no impact on the planet, but in fact it does, but the impact is long-term and long-lasting.

A long time ago, some scientists calculated that the earth can carry 1 trillion people, and this is also the limit of the earth. But with the continuous development of human technology, this number is also increasing.

The earth can carry at least 20 billion people, and about 30 billion is the limit.

Now the population of the earth should be 7 billion, I read an article according to scientists, the limit of the earth's population is 1300 trillion! If the earth has been destroyed like this, and if it is not protected, 1300 trillion is a bit hanging.

The population of the planet has reached an unprecedented level7.8 billion (2020 data)., estimated by the relevant agencies of the United NationsBy 2100, the world's total population could exceed 10 billion, the earth will enter a period of huge population.

The consequences of the explosive growth of the population have long been predicted, and in the late 18th century, the philosopher Malthus left this passage to posterity:The burden of the population has far exceeded the carrying capacity of the earth, and sooner or later, the earth will be overwhelmed and bring destruction to mankind.

In Malthus's time, the world's population may have been more than 1 billion, but Malthus still believes that eventuallyHumanity will exhaust all the resources of the planet and starve to death in a mass famine

The earth is so big, the total amount of resources can be calculated, which means,There can only be a certain number of people on Earth, not an infinite number。fromFood productionperspective, Harvard UniversityProfessor Wilsonthink, Earth'sThe maximum carrying capacity is about 9 billion to 10 billion people

But actually, fromEcology and Environmentpoint of view,Today's population of 7.8 billion is far more than the planet can handle, like the Amazon rainforest, has disappeared a large part in recent decades.

Our planet is actually sickThe ecosystem has begun to crumbleGlaciers in the North and South Poles are meltingTemperatures are getting higher every year, and extreme weather has become commonplaceAnd that's just the beginning, once we reach a tipping point, we don't know what kind of change the earth will be.

If the total population of the world increases to 10 billion, it is still unknown whether the food on the earth will be able to feed so many people, and no matter how advanced science and technology are, it is impossible for the output of crops to increase indefinitely.

And the most important thing is that as long as a person lives in this world, it will consume a lot of resources, and it will alsoGenerate a large amount of carbon emissions, along with someThe disappearance of forests and wetlands that regulate the earth's temperatureThe Earth's temperature will rise irreversiblyuntil the Earth is completely uninhabitable for human habitation.

10 billion people is really a lot, and maybe at that time, people will really want to dieBa appeared and snapped his fingers, although it is a little cruel, but at least some of the people can survive.

The upper limit of the population that the earth can afford is 15 billion, because if the population exceeds 15 billion, it will be difficult to survive.

10 billion, more than 10 billion The earth may not be able to withstand it, the environment inhabited by humans will be reduced, and it will be difficult for people to survive on the earth.
