In the imperial capital, in the centerpiece, One was watching a briefing. Pen Fun Pavilion wWw. ｂiquge。 ｉｎfo

It is written that "Sanitation No. 1" has a huge advantage in the control of environmental pollution, and has a huge advantage in absorbing dust, absorbing various pollution particles, absorbing heavy metals, etc.

Now there is a lot of smog in China, and many cities cannot see the blue sky.

Once the "Sanitation No. 1" is planted in a large area of the city, it acts as a lawn and a green space, which can absorb polluting gases on a large scale.

At present, the environmental quality of Qinzhou in Hainan Province is the best 12 (AQI), which is the first city in China for air quality.

To put it simply, some cities on Hainan Island do not have a wide range of industries, and they rely on coastal areas, where the sea breeze blows, resulting in better air quality. In some cities, there are more cars and many exhaust emissions, which are due to terrain, resulting in polluting gases and slow circulation, resulting in poor environmental quality.

In recent years, efforts have been made to control pollution and shut down some polluting enterprises, but it is extremely difficult and takes a long time to reverse the unfavorable environmental situation.

According to the estimates, three years of continuous planting can greatly improve the environmental quality of Huaxia, with an average of first-class air quality, 20 (AQI) for five consecutive years, and 10 (AQI) for 10 consecutive years.

At that time, the air quality in many cities in China will be greatly improved, and many heavily polluted areas will see blue skies again.

More than half of the region, air quality, comparable to Australia.

Of course, there are many disadvantages.

The most obvious is biological invasion.

Sanitation No. 1, fast reproduction, no natural predators, once a large range of reproduction, will lead to the extinction of many plants.

Once planted on a large scale, it will damage the local ecological environment.

However, there are also objections that lawns are mainly used in urban areas, and there is no so-called ecological environment at all, and they are planted as lawns in cities, which is less harmful.

Closing the briefing, No. 1 said: "Arrange the time, determine the time, and have a meeting to study the No. 1 Sanitation No. 1!"

The secretary nodded, began to schedule the time, and notified everyone.

............

At four o'clock in the afternoon, some officials of the Ministry of Environment and some academicians gathered together, and the meeting began with the arrival of the participants.

Academician Zhao took the lead in speaking: "Sanitation No. 1 is a student of mine who discovered it by chance. Originally, this was a medicinal herb, which was used to make medicinal food, spices, and condiments. It's just that he doesn't worry about the ingredients of the medicinal materials, safety first, and he goes to the laboratory to test the ingredients!"

"Then, another of my classmates, under the inspection, unexpectedly found that this plant actually has a large absorption effect on dust, polluting gases, etc., which has huge benefits for environmental treatment!"

Academician Zhao said about the experimental data one by one.

Data is the most boring, but in the world of science, it is the most convincing.

"It's just that it reproduces quickly, adapts to all kinds of harsh environments, and grows slowly in alpine and dry areas, while in some high temperature and humidity environments, it grows rapidly. And his lifespan, I calculate, is 100 days - 150 days!"

"And in some heavily polluted areas, life expectancy can be reduced to half, or even a third!"

"As for the mode of reproduction, it belongs to self-pollination!"

"I tried to stimulate, improve the species, make it less biologically invasive, but it failed. With the use of transgenic technology, the survival rate is less than one layer, the life span is less than 10 days, the nutritional development is stunted, and the absorption of polluting gases is weakened a lot!"

"Genetic modification failed!"

Speaking of this, Academician Zhao felt his own insignificance and helpless.

At the end of the twentieth century, the discovery of genetic technology made human beings arrogant, and they could arbitrarily modify some species on the earth, like God, to create all things.

Later, I realized how absurd and ignorant this idea was.

Human beings' understanding of genetic technology is very shallow, and some genetically modified species have many failures; even if they succeed, they are not safe. Genetically modified soybeans, genetically modified corn, etc., have always been rejected by mainstream humans. Although there is a lot of data proving that genetically modified soybeans are harmless, many people are still skeptical.

Academician Zhao is also transforming in many ways, wanting to make the No. 1 Sanitation perfect.

But as a result, it has been failing and not succeeding until now.

After Academician Zhao finished speaking, Academician Bai said: "Sanitation No. 1 has a significant effect in controlling environmental pollution, and I won't say much here." The main thing is biological invasiveness, and the destruction of other species must be taken seriously!"

"It adapts to various environments, its vitality is extremely tenacious, and it reproduces quickly, once it expands on a large scale, it will cause great damage to the earth's ecosystem!"

"I'm worried that a large number of planting sanitation No. 1, at that time, the environmental quality of China has been greatly improved, and I can see blue sky and white clouds, and the air is fresh, which is comparable to the world's advanced countries. However, when the environment is good, we have to pay for the invasion of organisms and the extinction of some plants!"

"It's hard to calculate this gain or loss!"

"Here, I agree with planting Sanitation No. 1 to improve the quality of the environment, but we must be cautious and cautious to reduce its drawbacks!"

Then, Academician Qian said: "The introduction of any species will attract biological invasions, but the cost is just a matter of size. You can't just choke on food and worry about biological invasion, so it's impossible not to introduce species!"

"Sanitation No. 1 has tenacious vitality and adapts to various environments, which is also the fundamental reason why it can absorb all kinds of pollutant gases to a large extent. Now some lawns and green spaces, some trees, have limited pollutant absorption, and once too many pollutants are absorbed, it will destroy plant health!"

"Theoretically, planting Sanitation No. 1 can attract biological invasion and destroy the ecosystem!"

"Actually, I think there are three factors that will inhibit biological invasion. First, Sanitation No. 1 is used to absorb dust and polluting gases, which greatly reduces its lifespan and inhibits its propagation speed and reproduction rate. ”

"Second, Sanitation No. 1 is mainly used as a lawn in urban areas, and in some heavily polluted areas, it is used to change the environment, or it is placed in the home to purify the air in the home. These areas are far away from traditional ecological parks, isolated in the city, isolated in the center of polluted gases, and have limited biological invasion!"

"Third, Sanitation No. 1 can not only be used to control environmental pollution, but also can be used for medicine, which has a wide range of uses. His usefulness, his versatility, makes it impossible to be an invasive creature!"

"My opinion is to expand the test area, and in some heavily polluted areas, polluting factories will take the lead in planting!"

Then one expert after another spoke up and spoke their arguments.
