After reading this task, Ding Yun didn't know if he was lucky or unlucky, how could he be lucky and come across a task to save mankind, and if he was unlucky, how could a random task be with her golden finger.

There is a vague fit.

Daughter's spring water is not related to reproduction.

However, Ding Yun did not dwell on this aspect, and she soon began to merge with the original body.

And use the consciousness chip to sort out the memory of the original body.

And then......

The specific causes and consequences are all known to her.

Since 500 years ago, the world has had a lot of obvious pollution due to the development of science and technology, whether it is air, soil or water.

All of them have suffered from various kinds of pollution to a greater or lesser extent.

For example, air dust pollution, enterprise exhaust gas harmful substance pollution, surface water pesticide hormone enrichment pollution, groundwater wastewater and compound pollution, solid waste pollution, compound pollution, soil fertilizer and pesticide white pollution, heavy metals and radiation pollution, electromagnetic radiation pollution......

In short, all kinds of convenient progress created by the development of human science and technology will bring pollution to the environment.

The difference is nothing more than a matter of how much.

And the question of far-reachingness!

Although this aspect has attracted the attention of various countries.

But it is not fully emphasized.

In other words, the degree of attention is not the same in each country, and the degree of attention is not the same in different regions.

But in most regions, the core criterion is that the environment must give way to development.

They feel that pollution can be left to future generations.

They are going to develop now.

These situations and ideas have not solved the problem of environmental pollution, at most it has been alleviated in some aspects, or the pollution rate is not as fast as before, but it is just that.

Over time, some pollution has become more ingrained, and even penetrated into the daily life of all people, beginning to affect human health, human body diseases, and human reproduction.

For example, there are more strange lesions, for example, the incidence of cancer has increased, and the fertility rate has decreased.

For example, the overall quality of newborns is not as good as in previous years.

The number of infertile people is increasing

The rate of neonatal malformations is increased.

increased rates of involuntary abortions, and so on.

It's just that because of technological advances, the average life expectancy of the population is still slowly rising, masking these problems.

Or rather, make these problems.

It doesn't look so sharp!

By 400 years ago, even if there had not been a large-scale war that had caused a large number of deaths among men around the world, the ratio of men to women in the world had still crossed the dangerous limit.

The male-to-female ratio reaches 0.8:1.

The male-to-female ratio of newborns has dropped to 0.7:1.

The results of the study at the time showed that the main reason was that men were more exposed to the environment, or that men were exposed to drastic changes in the environment.

Less adaptable than women.

Even the genetics are problematic.

It's hard to say whether it's true or not, anyway, that's what is generally described in the history books, so let's just think so.

This has been the case since it emerged.

It never turned around.

Environmental degradation has exacerbated the phenomenon, with an irreversible contrast between men and women that has not improved for years to come.

The gap is even widening.

But at this time, it is too late to engage in environmental protection.

Because there is hardly any area in the world that is free of pollution, the difference is nothing more than that there is less pollution in one place, more pollution in another, and some places are no longer suitable for human life.

The further you go, the greater the disparity between men and women.

Men have even become more precious beings.

A man can be pursued by dozens or hundreds of women, there is no way, the world is rare and expensive.

But fertility, reproduction and population problems.

But it is still a serious problem.

The shortage of labor can also be made up for by robots, but the population is not enough, so it is not a problem to build more robots, so since two hundred years ago, the world has launched the artificial human project, so it is not very accurate, to be precise, it should be the launch of the new human project, the use of genetic technology to create a population.

When the project began, they divided all humans into two groups, one was formed as embryos through the normal traditional model, and then conceived by artificial breeding machines, and this group of humans was called natural humans.

Another type is to randomly select two genes from the gene pool to synthesize new embryos, and this type of embryo is called a new human after becoming a human.

Generally speaking, natural humans have parents.

Although the new humans also have parents,

But their parents, some of whom may have been dead for many years, and some of whom may have dozens of new human children synthesized through genetic synthesis technology, so it is naturally impossible for those parents to take on the responsibility of raising their children.

Therefore, it is generally believed in society that new human beings do not have parents, and they are not raised by their parents, but are planned, managed and raised by the government.

They may be closer to the nanny robot.

At the beginning of the birth of new humans, natural humans wanted them to be more adaptable to the environment, so all new humans were artificially inserted into the gene chain of some gene fragments that were more adaptable to the environment, although this behavior made the number of men and women of new humans tend to be balanced.

It also makes them stronger than natural humans.

However, the additional insertion of gene fragments has greatly affected the self-reproduction of new humans, and even made them almost unable to give birth to offspring through the natural reproduction mode of the past.

Even if there is no flow, it is mostly deformed.

Proportion of children who are able to give birth to a normal child.

Probably less than one in 100,000.

Proportion of healthy children born.

There is only a 1 in 1 million chance.

This situation directly makes new humans basically not give birth and will not have children, but new humans synthesized by genes will still appear in a steady stream.

As a supplement to the underserved population.

This went on for many years.

It continued until natural persons became fewer and fewer, higher and higher status, protected, and became a new privileged class.

Continue until the new human beings participate more and more in all walks of life, and grasp the lifeblood of all walks of life, and continue until new human beings violate the law and study genetic technology.

The original body is one of the new humans, and it is also a new human who secretly violates the law and studies genetic technology.

Through research, the original body found that the lifeblood of their new human beings is completely in the hands of natural people, and once all natural people die, then the natural person genes in the existing gene pool will lose their sustainability.

And once the genetics lose their sustainability.

No new genes will be entered.

If the new human beings are artificially created, the diversity of the new human beings will be greatly limited, and the impact will not be great in a short period of time, but once it lasts for a long time for one hundred and eighty years, the genes of the newly created new human beings will definitely have genetic conflicts, and there will be a terrifying phenomenon of genetic collapse.

When the time comes, it will be the end of humanity.

Because of the gene synthesis human project, there was a defect from the beginning, and that defect is that the genes in the gene pool are all adjusted genes, and there is no original gene, which is said to be convenient for synthesis.

Save time and time having to adjust each synthesis.

It is not known whether there will be a problem with the direct synthesis of the original gene, but the modified genetic gene is definitely not suitable for long-term synthesis of humans, and it is certain that new original genetic gene regulation must be continuously added halfway.

Once natural humanity perishes.

Big problems are bound to arise in the synthesis of new humans.

After the original body discovered this crisis, coupled with the fact that the number of natural persons has fallen to six figures.

She took the risk.

The situation was reported to the main brain.

Then, of course, people did not take her advice at all, and decided that she violated the law's requirement that new humans should not learn and study genetic technology, and she was arrested and wanted.

Then the original body began to flee.

The latest is that she was attacked, badly wounded, and fled to the contaminated area, where she died.

Not long after, it was Ding Yun who arrived.
