Zhao Jingsi looked at everyone, and then said with some hesitation:

"In fact, to solve the problem of microplastics, there is a fundamental solution."

"Fundamentally resolved?" Liu Zhifan was stunned for a moment: "What way?" ”

Zhao Jingsi looked at Li Qingye with some hesitation.

Of course, Li Qingye knew what the method he was talking about, he waved his hand, and then spoke: "The method that Jingsi said is actually plastic decomposition bacteria, and the company has achieved a lot of results in this regard." ”

Hearing the news, the crowd was not too happy.

Everyone present is a smart person, and they don't look at things only for the good and not for the bad.

Li Qingye continued: "I think you have also seen the problem of plastic-decomposing bacteria, and in order to ensure that plastic particles in nature are broken down, it is necessary to unlock the genetic limitations of this artificial fungus and give it the ability to reproduce itself. ”

"In addition, once released into nature, it means that this fungus can no longer be destroyed, and I dare not guarantee that they will not mutate into bacteria that are harmful to humans or other organisms during the natural reproduction process."

Li Qingye paused: "And once the plastic decomposition fungus is released, the service life of most plastic products in human society will not exceed 3 months." ”

Grunt! A fine layer of sweat broke out on Qiu Yingle's forehead, and she once again saw the horror of a biologist.

Once again, there was a heated discussion.

Plastic products are a very comprehensive material for modern society.

From plastic bags, plastic boxes, plastic films, clothes, toys, plastic products, to interior decoration, electrical wires, vehicles, ships, airplanes, and even satellites and space stations, plastic is everywhere.

If you choose to release plastic-decomposing bacteria, it means that these plastic-based products will face a huge shock.

As long as Homo sapiens chooses to release, this kind of impact is almost unavoidable.

Now the choice in front of everyone is to let it go or not to let it go.

Liu Zhifan thought for a moment: "We need to consider alternatives to plastics, or protection issues. ”

Jiang Mingxuan, the head of the Ministry of Science, asked: "Zhifan, your Ministry of Industry should have an application catalog of plastic products, right?" ”

"Yes, I'll share it with you."

Liu Zhifan shared the plastic application catalog with everyone after a while.

Everyone was looking through it intently, because it was about the whole world, and it was about the hundreds of industries that needed to be adjusted within Homo sapiens.

Although Yau Yingle is now in charge of the entertainment department, she has been in charge of Siam for a long time, so she is more interested in another special branch of the plastics industry:

"Mr. Chairman, does plastic fungus also work on natural rubber?"

Li Qingye nodded: "It also has a decomposition effect, but the speed is slower, and the natural rubber will be completely decomposed in about 14~16 months." ”

Of course, 14~16 months here actually refers to a completely exposed environment to air or water, and the temperature and humidity are more suitable.

If you dry and hot tropical deserts, or extremely cold poles, thin air and plateaus with strong ultraviolet rays, in these areas, the decomposition rate of plastic fungi will drop by several times, or even dozens of times.

In addition, burying deep in the soil can also slow down the rate of decomposition.

When Yau Yingle heard this answer, she immediately understood that the natural rubber industry in Southeast Asia could not survive the attack of plastic fungi.

But Li Qingye still gave everyone good news:

"Although plastic fungi will break down plastic products indiscriminately, we still have some preparations, such as inserting dozens of targeted genes into fungal genes, through which the use of some specific agents and ingredients can inhibit its decomposition rate."

Qiu Yingle thought thoughtfully: "Is this so?" In this way, in fact, the service life of plastic products has decreased, but it can still be used. ”

But Jiang Mingxuan shook his head: "Although fungal inhibitors can be inhibited, they have health risks, and plastic products that come into contact with the body basically cannot be added." ”

Qiu Yingle said with a smile: "It doesn't matter, rubber tires, wire insulation, etc., you can use inhibitors." ”

Others also said their thoughts.

At present, the most affected application areas are actually plastic bags, plastic boxes, foam boxes, plastic films, plastic packaging bags, and chemical fiber clothing that come into contact with food.

"Are there any non-toxic inhibitors?"

Jiang Mingxuan replied: "Yes, but non-toxic inhibitors are degraded very quickly, and they usually only work for one or two weeks. ”

Discussions went on and on, and they found that they could only look for alternatives.

For example, the use of natural fibers to replace chemical fibers, including cotton, jute, Manila hemp, bamboo fiber, wood fiber, etc.

At the same time, aluminum alloy, stainless steel, wood, glass, etc. can also be used to replace the use of some plastics.

For the rest of the disposable straws, you can continue to use plastic, but you need to use a special storage box to seal and store, and once opened, you must use it within a few days.

After some discussion, they found that plastic is not irreplaceable.

As for the production cost of alternative materials, there is no need to worry.

For example, Homo sapiens' unique low-temperature glass technology, low-temperature alloy technology, and matte farms can produce large quantities of organic matter.

By switching to cotton, flax, jute, Manila hemp, wool, duck down, and leather for clothing, Homo sapiens' production costs can still be kept very low.

Taking Egyptian long-staple cotton as an example, the current area of cotton planting in Egypt is about 100,000~150,000 hectares, with an average yield of about 1 ton per hectare, and its export price is 5,000~6,000 US dollars per ton.

The export price of America's horse cotton is 2000~3000 US dollars per ton.

However, in the lightless farm of Homo sapiens, it can achieve a yield of 5 tons per mu, plant 6 stubbles a year, and produce 30 tons of cotton per mu per year, and the varieties can be chosen at will.

Moreover, the cost of cotton production is only 57 gold yuan per ton, which is equivalent to 114 US dollars per ton.

In this way, the use of cotton to completely replace chemical fibers will become lower in cost.

After all, with the soaring global oil and gas prices, the current price per ton of chemical fiber has soared to 3,800 gold yuan (equivalent to 7,600 US dollars).

This cost is more expensive than using Egyptian long-staple cotton.

Although Homo sapiens has its own petrochemical industry and many oil and gas fields, it does not mean that the price of imported oil and gas will be low.

After weighing the pros and cons, Li Qingye made a decision.

That is to release plastic fungus, and first solve the problem of microplastics that has spread to the world.

He instructed: "Zhifan, Mingxuan, you are responsible for this matter, prepare for the upgrading and transformation of the industry, of course, don't announce it to the public now, just make a plan internally." ”

Liu Zhifan and Jiang Mingxuan nodded.

Although the decision was made to release the plastic fungus, how to release it requires strategy and time.

Homo sapiens can afford to lose plastic, but other regions may not.

Especially in those developed areas, there are many industries that use plastics, and in the face of the indiscriminate attack of plastic fungi, those industries are unprepared and quickly fall into a state of shock.

Therefore, even if it is for show, Homo sapiens must be prepared to die and refuse to admit it, so that Europe, the United States and the Far East have nothing to say.
