Will the earth be overcrowded in n years?

No, there are generally two forms of population growth: "J" curve and "S" curve. The former must be in an ideal state: sufficient space and food, a suitable climate, no natural predators, etc., which is basically non-existent in the natural state.

Then the rest is the latter. That is, after the organism reaches the maximum value allowed by the environment, it will not increase. You can take a look at Malthus's population theory, although it is a bit pessimistic, but there is still some truth, just like Ma Yinchu's population theory.

No, because there is already a negative population growth in developed countries, that is, a certain degree of economic development and the improvement of the quality of the population. The population will be reduced.

Moreover, many developing countries will adopt some relatively strict policies to control population growth, which has become the consensus of developing countries.

I don't think so. Countries may adopt a number of policies until they are full.

Or there is a war between countries because of some factors such as land.

The population continues to increase, and the earth will not get bigger, and if there is no planetary migration, it will definitely be overcrowded!

No, if human beings reach overcrowding, science will no longer know how far it will go, and it may develop on other planets. Or develop hanging gardens.

No, humanity has recognized the huge problem of overpopulation, and many countries have already taken measures. For example, China's family planning, India's birth control program, and so on, many countries have reduced population growth, some have achieved zero growth, and Germany in Europe has negative growth.

No. When the time comes, they will immigrate to other planets.

No, people don't want to have children anymore.

No, it's all planned for family.

The life and death of the earth is based on whether life can reproduce on the earth. Life on Earth does not thrive with the light and heat of the sun. If the activity inside the Earth ceases, it will become a dead planet, volcanoes will never erupt again, plate activity will stop, ** will disappear, hydrospheric activity will flatten out, and more importantly, the magnetic field will disappear, all kinds of high-energy particles will radiate directly to the ground, and all kinds of life will be difficult to survive.

And all that. Therefore, the future life of the Earth will not be the 5,06 billion years that the Sun will be able to provide light and heat stably.

If the structure of the Earth's core is traditional iron-nickel, then life on Earth can enjoy the protection of the Earth's magnetic field for another 4 billion years. If the Earth's core is a uranium fission reactor, as a new theory suggests, since the diameter of the uranium core has shrunk from about 13 kilometers to 8 kilometers in the past 4.5 billion years, that is, 75% of the uranium has been consumed, so it is calculated that the uranium fission reaction in the Earth's core can only last for another 2 billion years, that is, the Earth will become a dead planet in 2 billion years.

Scientists judge based on the ancient rocks on the earth: the earth is about 4.6 billion years old, it has entered the middle age of the earth, and it can last for about 4.6 billion years!

If humans continue to destroy the earth, it can only last for about 100 years at most!

It is estimated that the Earth has survived for 4.6 billion years. Scientists believe that if the Earth is allowed to move freely, it may exist forever, but if other external factors interfere with it, the Earth may have an end of life. The external factor is the sun in the first place, because it is the closest planet to the earth and can have a destiny on the right earth That is to say, all the energy and power on the earth come from the sun, and once the sun has three long and two short, it is bound to affect the earth.

Before the 30s of this century, people always thought that the sun would one day burn out, turn from white to orange and then to red, and finally become a dark star that was silent, but its brilliant life. In the 30s, when physicists learned the mystery of the sun's light, the situation was very different. It turns out that the Sun's energy comes from its thermonuclear reactions, and the Sun's lifetime will pass through the gravitational contraction phase, the main-sequence star phase, the red giant phase, and the compact star phase.

The main sequence phase is the period of stability of the Sun. This phase will last for 10 billion years. At present, the sun is only halfway through and is in middle age.

Once the Sun reaches the red giant stage, then the end of the Earth is coming. Of course, this is billions of years away.

Some scientists believe that the Sun may have a brother, a companion star of the Sun, which orbits the Sun day and night, and turns away from the Sun every 26 million years.

The nearest place to come"Make waves"Its strong gravitational pull will cause a large disturbance of many comets, and 1 billion comets will be on a rampage in the solar system, and the Earth and other planets will become these comets"Target"。If the mass of the comet that collides with the Earth is large enough, the consequences are unimaginable: the extinction of light organisms and the upheaval of ecology; Heavy landslides and earth cracks, the earth"Broken bones"。

However, this solar companion star, which could bring misfortune to Earth, has not been discovered, although many scientists believe it exists.

According to current scientific detection, the life span of the earth is about 27 to 3 billion years, and the existence of human beings is certainly far less than that of the earth, and the current problem of human beings is human beings themselves.

The Earth has been around for about 4.6 billion years. And the life span of the sun is only 5 billion years. When the sun becomes a giant star, the end of the earth will come. Of course, it will also affect the survival of human beings.

According to scientists' research, the earth's lifespan is still billions of years, and it will not affect the survival of human beings in the future.

The life span of the earth is still 5 billion years, and this will not affect the survival of human beings in the future.

The Earth has 4 billion years to live, and it will always exist if there is no alien star impact. It will not affect the survival of human beings.

It is precisely because the life span of the earth is still unknowable and inaccurate that we must work hard for the longer the earth lives, after all, the destruction of the earth is the destruction of human beings, so we should usually protect the earth, protect the environment on the earth, and really regard the earth as the mother who gave birth to us, so that the unknown unfavorable situation can become a knowable favorable situation, so that our earth can always accompany us, so that the earth can be maintained for a long time, and do not let the earth be destroyed because of our reasons.

The life span of the earth is very long, human life is negligible for the earth, before humans, there were many living things, so there is no need to worry about the survival of human beings.

The development of evolution until the evolution to the present civilization. Everything in the world has life and death. With our current knowledge, the earth cannot always give birth to human development, so how long can humans live?

and nature in harmony. It seems that this stage has already been passed in ancient times, but in our ancient times, it was said that heaven is conquering the sky, so this argument has been deeply rooted in people's hearts. Human technology is constantly evolving to better transform nature, and if it cannot be completely reversed, it can prevent humans from being vulnerable to nature's attacks.

It turns out that with the current technology of mankind, it is indeed very vulnerable in front of the big nature.

Whether it's humans or Earth, everything dies one day. Something starts from the moment it is born, and it indicates that it will disappear completely at some point in the future. Stars are born and destroyed at every moment in the universe, and the Earth is just one of many stars in the universe.

The universe is 13.6 billion years old, and the Earth is 4.6 billion years old. Humanity is just a million years. Earth's last overlord, the dinosaurs, survived on Earth for 200 million years and still hasn't escaped the bad news of being destroyed.

If you don't take into account the influence of external forces, then now that the earth is in the middle and young age, we don't have to worry about the death of the earth's lifespan, but we can After all, everything on Earth needs the sun, so please don't ignore one of the most important factors, which is the sun. Without my sunlight, most living things on Earth would go extinct, including humans. However, according to the science of science, the sun is currently in middle age, and its life expectancy is about 5 billion years.

5 billion years is too long for us to imagine what will become of humanity at that time, I don't know if it exists, besides, humans may not be able to survive the earth for so long because the earth cannot imagine humans for so long. The current global environment, as well as the greenhouse gases emitted in human production and life, global warming has become the most serious problem facing us at present. The scientific family believes that in the next 1.5 billion years after the earth, the surface temperature of the earth will gradually increase, and places with higher equatorial temperatures like the earth will no longer be suitable for human habitation, and by that time the earth will be completely unsuitable for human life, in fact, this is the most conservative estimate, and it is likely that 1.5 billion years is too long.

The earth's resources are almost exploited. If humans are unable to exploit other sources of energy, they can only be forced to migrate to other stars, but it is not easy to migrate to other stars. The scientific family believes that life on Earth will become extinct in 25 million years, which means that the next mass extinction is closer and closer.

The most recent time in science is also 25 million years, which does not include other human factors, such as war. If you think about it, maybe this time it will be earlier.

According to scientists, humans can live on Earth for about 5 billion years.

As long as human beings protect the environment, conserve resources, and care for Mother Earth, they will live on it for a long time.

Humans can still live on Earth for many more years. Because the earth still has a long lifespan.

If humans do not continue to destroy the environment, they can survive on the earth for many years, and if they continue to destroy, then they can only survive for a few years.
