I make a popular science video and all the emperors learn from it!

[The video continues. ] .

[Coincidentally, there are not only countries that are addicted to drinking syrup, but also countries that like to eat grass. ]

[The grass listed as a drug by China is slowly destroying this country. ]

[It is Yemen. ]

[A country that could have become rich from oil, but the whole nation is lying down at home "eating grass" to live. ]

[What kind of grass can make people so addicted? ]

[Khat, also known as Arabic tea, is a plant produced in East Africa and the Arabian Peninsula. ]

[Its stems and leaves contain natural ammonia and chemical cathinone. After chewing, it stimulates the central nervous system of the human body, making people excited and addicted. It is a soft drug. ]

[As early as the 13th century, Khat was used to help the poor resist hunger and fatigue. ]

[But long-term chewing can lead to decreased immunity and malnutrition. 】

[Therefore, Khat is also known as the East African poppy. 】

[Since the 1970s, the area of ​​Khat cultivation in Yemen has grown rapidly, from less than 100 square kilometers at the beginning to more than 1,000 square kilometers today. 】

[Since Khat consumes 40% of groundwater, its growth is very lethal. 】

[Any land planted with Khat, no matter how fertile it was, will have its soil structure changed by it. After planting other crops, the harvest will become very low. 】

[The characteristics of Khat and the crazy desire of Yemen for it have raised its value for a time. 】

[From the initial 0.5 US dollars, it has soared to 20 US dollars now. 】

[The Yemen people, who don’t have much income, face such high prices, which makes them forget the real needs of their bodies and start to squander their remaining land resources. 】

[This also leads to the annual output value of Khat being eight times higher than that of wheat! 】

[Yemen, which cannot be self-sufficient in food, has become the poorest country on the Arabian Peninsula. 】

[Its neighboring countries are all very rich. 】

[Among them, the per capita annual income in Qatar reaches 68,800 US dollars, while Yemen is only 690 US dollars. 】

[Also a country that can get rich from oil, Yemen also has multiple gold deposits, as well as the exit of the Suez Canal to the Indian Ocean, the Gulf of Aden and the Red Sea. 】

[Yemen, who has such rich resources, chose to lie flat. 】

[They work very short hours a day, starting work at 9 am and leaving get off work at 2 pm. 】

[After work, most residents start to gather together to chat and chew Khat. 】

[They propped up the pillow with their arms and their heads with their hands, and lay there enjoying themselves for as short as four or five hours, or as long as six or seven hours, until their excitement reached its limit and they became tired and drowsy. 】

[Basically every home has a separate room for them to chew khat. 】

[In Yemen, 90% of men and50% of women are obsessed with Khat, including many women and children. 】

[Even public officials chew Khat when they are performing their duties. 】

[However, not all Yemenis are obsessed with Khat. 】

[These people understand the harm Khat brings to themselves, and find the code of wealth in it, and make a rich life through the income from selling Khat. 】

[The behavior of Yemen's people eating Khat and lying down has also been warned many times by the United Nations. 】

[However, due to the excessive dependence of local people on Khat, it is impossible to restrict the trade of Khat. 】

[Seeing Yemen being eroded by Khat, its neighbor Saudi Arabia directly designated it as a contraband, and once anyone found engaging in Khat trade was directly sentenced to death! 】

[In countries such as Dubai and Abu Dhabi, anyone who possesses Khat in their country will be sentenced to life imprisonment. 】

[Ye's lying flat feeds another region. Ethiopia has made a lot of money by exporting Khat to Ye, but as the scale of cultivation continues to expand, I wonder if it will follow in Ye's footsteps in the future. 】

"Good fellow, eating grass can also become addictive, are they all sheep¨々?"

"My goodness, this kind of grass is very harmful to people."

"They don't even have enough food to eat, no wonder they are so poor."

"......"

The ancients were stunned.

It is understandable that cough syrup is addictive, as it contains wine, but what the hell is this eating grass!

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

The Three Kingdoms period.

Cao Cao raised his mouth and smiled evilly.

“．¨ Hey, I will order people to find Chat grass now and persuade the people in other territories to plant it.”

Having seen the terrifying destructive power of Chat grass, Cao Cao was tempted.

This thing is more powerful than any weapon!

Not only will it make people lazy and have no fighting spirit, it will also pollute the land and cause a serious reduction in the yield of crops planted there.

When Cheng Yu heard Cao Cao's words, his eyes lit up!

He was just about to persuade him, but he didn't expect the prime minister to understand it himself!

As a famous poisoner in the Three Kingdoms, he immediately thought of the same plan as the prime minister when he saw Chat grass.

Cheng Yu smiled and congratulated: "Prime Minister, this plan is very good, but I'm afraid others have already been on guard."

Cao Cao was dumbfounded. He turned his head in surprise, "I was just joking, I didn't expect you really meant it!"

"This may be against the harmony of heaven and earth, shortening my life span, not right. (Good Li Zhao)”

He never expected that his advisers would take his words seriously.

It’s really vicious!

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

Ming Dynasty.

Zhu Yuanzhang was sweating.

“Planting this grass can actually reduce the yield of crops planted later.”

“We must not let this grass flow into the territory of the Ming Dynasty!”

Zhu Yuanzhang didn’t want the people of the Ming Dynasty to become like the country in the video.

The people eat grass every day, and even don’t care if there is not enough food.

Zhu Yuanzhang shouted: “Pass on my order, strictly check the customs, and never let this grass enter the Ming Dynasty. Once someone is found planting and selling this grass, he will be directly dragged to the street and beheaded!”.
