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 are very rich in chemicals. 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 for making bricks. The bricks made from them are strong and are 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 is a joke about Wu Hao and his friends using sand to burn bricks to build a lunar scientific research station on the moon. Everyone thought that building a lunar scientific research station on the moon was a very high-level matter. Who knew that Wu Hao and the others were baking bricks on the moon? How is this different from that on the earth?

Just like that famous meme, humans can't get rid of boiling water in different ways. In addition to hydropower generation, whether it is a thermal power station, a geothermal power station, a nuclear power station, or even a solar molten salt power station, they all boil water in a different way, 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?"

It all adds up to about 40,000 to 50,000 acres. Shen Ning answered.

It is not easy to plant such a forest area of ​​40,000 to 50,000 acres in this desert Gobi. Professor Zhang Chengwang affirmed.

Yes, this has to be said to be a miracle. Professor Huang Shiwei also said with emotion.

Yang Fang continued with a smile: "Now this forest area continues to expand, almost by 5,000 acres every year. It is expected that in a few years, the Gobi Desert near our park will be Wear green.”

Okay, with this forest area, it's like driving a nail in this desert. With this place as our support, we have the confidence to conquer this desert.

Speaking of this, Deputy Director Cheng looked at Wu Hao and couldn't help laughing: "Forget it, I'll leave this to you. I believe that with your efforts, the desert here will be covered with green. We Let’s concentrate on facing the harsh forms in other regions.”

Quack, quack…

Following several cries, several pheasants flew up from the forest area, and then flew away into the distance.

Oh, there are so many wild animals. Huang Shiwei pointed at a few rabbits popping up over there and said.

"Haha, since the formation of this forest area, we have seen many animals here, including wolves, jackals, leopards, deer, antelopes, sheep, foxes, rabbits, eagles, pheasants, eagles, etc. .

Last year, an animal research and protection organization from a university in Beijing conducted a survey here. More than 30 kinds of animals were found alone. It can be said that this forest area has become the habitat of these animals in the Gobi Desert. A haven and a paradise. "Yang Fang smiled at everyone and said.

“In the past, we would go to this forest area to play after get off work and on weekends. Because the environment here is good and cool, many people would choose to camp here.

But later, people discovered wolves, jackals, leopards and other large carnivores here one after another, so no one dared to camp here, and no one dared to come here at night. Usually when I come here on weekends, I always come in groups and I don’t dare to come alone. "

It can be seen that you all protect this forest area very well. I have been looking at it for a long time and I haven't found any garbage. Professor Zhang Chengwang said with a smile.

Haha, on the one hand, this is because everyone is conscious, and on the other hand, we will also organize relevant volunteers to clean up the garbage regularly, so the environmental protection is relatively good, and basically there is no garbage to be seen.
