Chapter 2999 The Contradiction between Man and Nature
Wu Hao, on the other hand, continued with a smile: "In order to prevent the filtration capacity of the sand used for filtering and infiltration from weakening over time, we regularly close the gates on both sides and replace the sand.
These sands contain very rich chemicals, and we will filter, recycle, and then dispose them harmlessly to avoid environmental pollution."
Speaking of this, Wu Hao half-joked at Nan Cheng: "Actually, these sands are best used to bake bricks. The bricks produced are strong and very suitable for paving roads or construction.
It’s just that the cost is too high and it is difficult to popularize it on a large scale.”
Hahaha……
Everyone laughed when they heard Wu Hao's words. This was a joke, making fun of Wu Hao and the others who used sand to burn bricks to build a lunar scientific research station on the moon. They all thought that they were building a lunar scientific research station on the moon.
Station is a very high-level thing. Who knew that Wu Hao and the others were baking bricks on the moon? How is this different from the earth?
Just like that famous meme, human beings can't get rid of boiling water in different ways. In addition to hydropower generation, whether it is thermal power stations, geothermal power stations, nuclear power plants, or even solar molten salt power stations, they all boil water in different ways.
Boil water, but the way of boiling water is different.
After the laughter subsided, Professor Zhang Chengwang asked with a smile: "How big is this Populus euphratica forest?"
The total total is about 40,000 to 50,000 acres. Shen Ning answered.
It is really difficult to plant such a forest area of 40,000 to 50,000 acres in this desert Gobi. Professor Song Piaoliang said.
Everyone laughed when they heard the student's question.
"In the future, you will also go out to the forest area to play during work and weekends. Because the outdoor environment is bad and cool, few people will choose to camp there.
Besides, it’s difficult to raise those fish small, and it would be too troublesome to raise them again if they are eaten, so no one wants to take care of them.”
But no matter what, do you have the right to prevent other tourists from visiting the Gobi desert? That is their freedom and right. Besides, it is also a way for the locals to get rich. You can also cut off other people's financial paths, right?
"
Each of these students became excited and stood on the shore and actively pointed at the Zhazi Cave.
Yes, that is indeed a miracle. Professor Song Piaoliang also said with emotion.
When it's so small, should it be taken out and eaten? Suddenly one of the students licked their lips and asked.
Haha, on the one hand, this is because we are self-conscious, and on the other hand, you also organize relevant volunteers to clean up the garbage regularly, so the environmental protection is relatively bad. Basically, you can see what kind of garbage you find.
As long as you hope to establish an ecosystem outside the river, it will also provide food for some birds outside the river. At the end of the day, those fish still need you to put in food, so those who come quickly are those who need it.
Already."
It can be seen that their family's protection of the forest area is very bad. You have been looking for a long time and you haven't found any garbage. Professor Huang Shiwei said with a smile.
Following a few cries, several pheasants flew up from the forest area, and then flew towards Zuru.
Quack, quack, quack…
Wu Hao smiled and shook his head: "Does anyone really want to eat the fish outside? Although the sewage has been purified at all levels, there is still a certain degree of pollution, so the fish growing outside will naturally
No one wants to eat it.
That's one of the main reasons why you hate tourists visiting there. It's not that some tourists are of poor quality and litter everywhere. When the wind blows, it's everywhere. The area outside is too small and it's really difficult to clean up.
Play? Everyone has the answer.
After all, we fish only for food, but for fun."
So there is no fish mother outside the water? Professor Song Piaoliang asked in surprise.
When talking about that, Wu Hao changed his tone and said: "Of course, it also depends on whether there is garbage. For example, when the wind blows, there will be less garbage floating to your place.
After all, there are really many places to fish in the Gobi desert in the northwest. Therefore, the fish outside naturally attracts the interest of few people, so not many people come to fish every weekend.
Last year, no animal research and protection organization from the junior high school in Beijing conducted a survey there. There were not more than 80 species of animals found there. It cannot be said that that forest area is like those animals in the Gobi desert.
It is a safe haven and Garden of Eden." Wu Hao smiled at everyone and said.
Yes, Wu Hao nodded with a smile and said: "Because there are fewer and smaller fish there, naturally it attracted some colleagues who like fishing, and gradually there were fewer of them.
It's bad, without that forest area, it's like driving a nail into that desert Gobi. Without that outside to rely on, you won't have the confidence to conquer that desert.
Oh, it’s still big. Professor Huang Shiwei said in surprise as he looked at the white shadow flashing past the water.
Wu Hao continued with a smile: "The forest area is still expanding now. It is probably expanding by 7,000 acres every year. It is expected that in a few years, the Gobi Desert in the distance of your park will
They will all be clothed in green."
Speaking of that, Deputy Director Cheng looked at Yang Fang and laughed uncontrollably: "Forget it, let's leave it to them. Do you doubt that with their efforts, the desert outside will be covered with green?
Yes, you should concentrate your efforts to face the harsh conditions in other regions."
Hehehe...
There's no bad little fish out there...
Speaking of that, Wu Hao seemed to suddenly think of something, and then said with a smile: "Yes, no one has thought about them yet. They are only for eating, but for playing."
"Haha, since before that forest area was formed, you have seen very few animals there, no wolves, jackals, leopards, no deer, antelopes, sheep, foxes, rabbits, no eagles, pheasants, and eagles.
etc.
However, no one has found wolves, jackals, leopards and other small carnivores there one after another, so no one dares to camp there, and they even dare to come here in the evening. I usually come here on weekends.
They all came together, but they dared to come alone."
The relationship between nature and people, and the relationship between the environment and tourists are topics that must always be discussed. Deputy Director Cheng sighed: "Theoretically speaking, there are contradictions between the seven, but in reality
But they are very contradictory. How to activate the relationship between the seven so that we can work together harmoniously is a difficult problem."
Oh, there are so many wild animals. Zhang Chengwang pointed at a few rabbits popping up here and said.
Wu Hao smiled and explained: "Haha, those are some of the seedlings you released in the experiment. They are mainly freshwater fish, not carp, grass carp, catfish, tilapia, lobster and the like.
