The term food security in the international sense was coined at the first Food Summit of the Food and Agriculture Organization of the United Nations (FAO) in Rome in November 1974...... In 1972, world cereal stocks were only 175 million tonnes, compared with 31 per cent in developing countries, which account for about three quarters of the world's population......"

Xu Xiandong was talking eloquently on the stage, and a table and data also appeared on the projection.

The class suddenly entered the main topic, and the large classroom was silent.

At the beginning of the course, Zhang Xun concentrated on making wood carvings without paying attention to external objects.

These boring knowledge may not sound good or interesting to the rest of the students, but for Zhang Xun today, he has gradually liked to absorb this knowledge.

Even if he is destined to not be an expert or scholar in any field, he can at least have a basic understanding of it through study.

Zhang Xun's serious appearance was very infectious, and the short-haired girl next to him gave him a strange look, strange to say, she was the first to sit here but seemed to have no interest in the class on the stage, and had no intention of listening.

These classes tend to last a few hours.

If you don't listen to lectures, you can't play with your phone, and you can't sleep, then it will be quite boring.

The short-haired girl didn't seem to be tormented by this pain, she just sat awkwardly, not as if she was listening to a lecture, but not against discipline.

He sat in silence for dozens of minutes.

The total duration of this class is very long, so a short break is arranged in between.

"There have been many global food crises, such as those in the 70s of the 20th century and ...... Well, let's take a 10-minute break between classes. ”

Xu Xiandong looked at the time, the time calculation was a little wrong, he stopped talking and took a sip of water.

The students below began to go out in order, and the classroom was suddenly filled with a relaxed atmosphere.

"Whew. ”

Zhang Xun exhaled and rubbed his sour eyes, normal people would be very tired if they maintained a high concentration for dozens of minutes in a row, but perhaps because of meditation, Zhang Xun only felt tired at the physical level, and his mind was still relaxed.

He turned his head to look to the side and saw the short-haired girl staring at him silently.

"You're serious. She said in a narrative tone.

“…… Thank you. Zhang Xun said politely.

"Are you interested in any of this?"

Faced with this question, Zhang Xun hesitated, sighed, shook his head, and then said, "But there are some things that you are not interested in and want to learn, right?"

"Makes sense. The girl nodded, still cold and frosty.

"What about you, I don't think you're listening......," Zhang Xun asked, the two of them stuck in the sea of people, and they were not outstanding at the moment.

“……”

Zhang Xun looked at her closed lips and expressionless face, and suddenly felt that the other party didn't want to talk to him, and threw two rems at him.

"Then let's talk about me. Zhang Xun asked tentatively, and he keenly felt that the other party did not seem to be willing to talk about herself.

"Good. ”

Well, this time she agreed quickly and perfectly.

There is a kind of person in the world who really can't chat, and it just so happens that both of them belong to this list, so after deciding to talk about Zhang Xun, they began to stare at each other without saying a word.

It seems that they are all hoping for the other party to get up and come out.

The staring lasted for about a minute, and the short-haired girl blinked, finally mustering up the courage to say, "You don't look like a student." ”

“…… You seem to have said that before. Zhang Xun was silent for a moment, and kindly prompted.

The short-haired girl was obviously stunned, but this time a bit of a dynamic expression finally appeared on her face, and she said with some confusion: "I said it?"

"Not bad once, exactly. ”

"I'm sorry. ”

"It doesn't matter. ”

It's all back to square one.

"Why are you not a student?" was silent for a while, and finally remembered a topic that had not been talked about.

Zhang Xun thought for a while and felt that there was nothing to hide, so he leaned back in his seat, looked ahead, and said, "I have some questions and want to ask Professor Xu for advice, come to the lecture to see if there is a chance." ”

"Then you don't have a chance. ”

"Why?" Zhang Xun asked in surprise.

The short-haired girl shook her head slightly, and the straight and well-defined strands of her hair were like a vertical rain curtain across the earth.

"Professor Xu needs to have a meal with the school leaders after the lecture, and there is a less formal meeting in the city to attend after the meal, and the meeting is about four o'clock in the afternoon according to the schedule, but it is customary to overtime, I estimate that it will be five o'clock, and there is a private dinner in the evening, and I always have to eat until eight or nine o'clock. She spoke slowly, as if she were a treasure, and her words were clear and convincing.

Zhang Xun was shocked at that time, got up slightly and asked solemnly, "How do you know so clearly?"

"Because I am Professor Xu's assistant and a miscellaneous student. The short-haired girl replied with a blank face, as if to say something innocuous and trifle, but of course, it was indeed a small thing.

However, it was a trivial matter that made Zhang Xun's eyes sullen, and His Majesty the young King calmed down and held back for a long time before he said, "Long admiration." ”

"Aha?" she was stunned.

Jingle Bell ......

I have to say that the school bell in college has a kind of back-to-basics realm, not as fancy as in middle school.

The large classroom slowly quieted down again, and Xu Xiandong continued to narrate the food crisis.

And the two drops of upright water in the sea of people continued to talk seriously.

"Helping students and ...... I don't know much about this, but why are you sitting here like this?" Zhang Xun was really at a loss.

The short-haired girl suddenly sighed and said in a painful tone, "I'm willing." ”

Tut.

It's hard to buy people with money, Zhang Xun is really speechless about it.

However, thinking that the other party had no reason to deceive himself, Zhang Xun asked without giving up: "Is it really that tight?

"No, I can't. ”

"Why don't you be accommodating, raise your hand, and let me try it in?" Zhang Xun felt that he could fight for it, the republic, the humane society.

The girl frowned and said unhappily, "No." ”

Zhang Xun pursed his lips, and he no longer insisted, he was just stepping on the point today, if he had to see it, it would be a big deal to owe Chen Du personal favor to ask him to introduce him.

Probably thinking that she was too indifferent, the girl hesitated, and suddenly said, "What do you want to ask?"

"You?" Zhang Xun glanced at her suspiciously, thought about it for a while, and then said.

After speaking, the other party looked at him with a strange expression: "I didn't expect you to ask such a strange question." ”

After a pause, her eyes twitched in the round frame, as if she was thinking, and after a few seconds in total, she replied, "In the case you hypothetize, there is only one best way to solve the problem at the root." ”

"What?" Zhang Xun perked up.

I saw her good-looking pink fleshy lips open and close slightly, and a cold toothy light flashed: "Aggression." ”
