Current status of the situation

A UN report, the United Nations Organization says that the population in the world increases exponentially. Today we are about  8,000  million people and it is expected that by 2040 there will be 10,000 million . According to these data, there will be about 2000 million more people during the next decades.

On the other hand, certain studies differ from these data justifying  two facts: and the progressive aging of the world population and the deceleration in the level of fertility.

A very frequent question is that it will happen in the future with overpopulation. We will deplete the planet’s natural resources for so many people? We will run out of space? What about the solutions that people really expect and what happens with the interstellar or crazy colonization of other worlds?

Definition of overpopulation

The  overcrowding  is a demographic phenomenon that is formed when the population density is high in an area. This implies that negative consequences arise such as famine, damage to the environment and others.

Overpopulation is a very important problem because the population in the world increases approximately 200,000 people per day.

In the last century there have been improvements in health, hygiene and of course, in technology. These improvements have made it possible for the life expectancy to be longer and better, being an important aspect that is contributing to the growth of the population. Some studies and sectors of the society arrive to affirm that  the overpopulation is a very serious problem that can end the human race.

A myth or reality

There is a fear that has spread enough that says that the increase in human beings on the planet leads to greater poverty of this.

In the eighteenth century, the demographer  Thomas Malthus  warned that the constant increase in population would lead to a deficit in the supply of food worldwide. Nowadays, that affirmation has been completely denied and leaves it far removed from reality. According to data compiled by the UN for Food and Agriculture, despite the recognized increase in the world’s population, food production has been growing, in the same way that there has been a continuous decline in poverty throughout the world. the world.

Contributions of humans to the world

A human being is not a burden for the world, it is not an expense, but a person capable of generating wealth that benefits the whole of society

Birth restriction as a solution

In recent times several ways have been considered to curb overpopulation. For example, we highlight the well-known birth control policy that has been established in China , where it was only allowed to have one child per couple (now it is already allowed to have two children per couple). After many years, it was found that this restrictive policy did not obtain the expected results in terms of population reduction. The reason it did not work was that Chinese women who wanted to have more than one child decided to give birth abroad.

The solutions that arise

Many experts who have devoted themselves to this topic have mentioned the negative effects caused by overpopulation, such as hunger, wars, unemployment, depletion of natural resources, etc. and at the same time they have also presented some possible solutions to eradicate it, such as, for example, the option of reinforcing training on sexual education on the part of young people or the tax exemptions or much more extreme of the obligatory chemical castration of newborns. of several generations.

Will we run out of space? Will there come a time when so much food can not be produced to satisfy all humanity? Will the natural resources of the planet be finished? The answer is simple. If we continue as before, consuming all the oil in the world and polluting oceans and the atmosphere, it is very clear that it is not. It is expected that a hundred years from now the situation that the earth is now experiencing will be reversed thanks to renewable energies, which are increasingly taking a leading role, to measures against pollution and research in the production of food as farm fields. underwater, etc. Of course, we will have to wait until the situation becomes quite unsustainable for governments to act accordingly.

Will we continue talking about the future of overpopulation?

Undoubtedly, overpopulation remains a very important issue in today’s society. If decades ago it was some prestigious demographers who predicted a great amount of catastrophes for the world because of this problem, nowadays this issue continues to make people talk. The overpopulation is not only present in books, for example, but also in many film productions. Examples of this are the films of  The Hunger Games  and  La Purga.

Hunger Games, only one survives

In the future, yes, thanks to advances in technology and science (more vertical buildings, underwater, more sophisticated farming fields and farms, more renewable energies, etc.) we will be able to reverse this situation that is now taking place in the world of planetary wear and tear and both overpopulation and global warming will not be a problem. We hope that we do not now reach a point of no return that does not allow us to recover the earth’s atmosphere and natural resources.

Colonization of Mars

As happens to the moon, Mars has its pros and cons to colonize it. For example, Mars could be further away (225 Mn Km at its closest point) but with the current chemical propulsion systems it would only take 6-7 months to reach with a minimum energy cost. In addition, it is approximately the same size as the Earth, which would mean that we could almost duplicate the area of ​​life that we currently have. However, like Earth, Mars has its own regions that could not be inhabited. The recent discovery of liquid on Mars, which may be water or not, is also a good indicator along with the rich content of iron in the soil that is potentially habitable within certain parameters. The pros, however, are neutralized by the cons. The gravity on Mars is only 38% of that of the Lands, causing the colonists to be much higher than the average over time and losing muscle and bone mass, causing the bodies to weaken, which is not good for the permanent colonization of any place. In addition, due to the lack of a strong magnetosphere, the Martian surface is bombarded by the radiation emitted by the sun and buildings should be built to protect us from it.

Another decisive factor is the fact that the surface of Mars, which is 52% farther from the Sun than Earth, is much colder than Earth, where our average here is 57.2 degrees Fahrenheit, the average on Mars is -124.6 Fahrenheit In addition, due to the lack of a strong magnetosphere, as the Martian surface is bombarded by radiation emitted by the sun, which makes life a constant struggle to stay protected from radiation.
