  Students in the classroom were making a fuss. Students who listened to the meaningful words of the professor the other day had heard the news about the Cheonan incident two days later. Many students thought so he was . Few people thought he was a spy. Now, even male students who looked down at the professor were thinking of his story fresh. Besides the so-called Muhammad Kansu incident, there was no incumbent professor who became a spy.

  When the professor came in, the students whispered in unison. Some students came to visit after hearing rumors from the next department, and some laughed quietly. "Professor, did you become a naturalized citizen like Professor Muhammad? Is your last name 'Gama' also rare in Korea, by any chance, a North Korean last name?" one female student jokingly asked. Gamamusa shrugged. "I came here because it is the cause of the nation." The students burst into laughter.

  The professor opened the bag and naturally took the world map and taped it to the blackboard. The students were puzzled to take out and paste the map like last time. "In this session, we will learn about demography as well. Don't just think it's TMI, but think for yourself. This is a compilation of all the classes from the previous session." On the blackboard, the professor wrote, 'Population and the flow of food.'

  "As I said in the last class, the so-called 'food self-sufficiency rate' is relative. When one side is overflowing with food, the other side is bound to be insufficient. However, as I already said, the food self-sufficiency rate of humans converges to 100%. In fact, it remained that way until the 15th century. Up to this point, the per capita gdp in the world was similar. Even the wealthiest regions in the world were two to three times the per capita gdp of other regions at best. This was the same in Mali, Ethiopia, and Europe and China in Africa. Everyone led similar lives except for hunter-gatherers and nomads."

  The professor wrote down the words '15th Century' on the blackboard. He then wrote 'Columbus' next to it. "…the situation changed beginning with Columbus's discovery of the New World. After Columbus discovered the New World, the conquerors who went there found corn." The professor took out a piece of chalk and drew a line on a world map to connect Mexico to Spain in the Mediterranean Sea, and this time to the midwestern part of North America.

  "..Corn, which was growing on Mexico's subtropical plateau during the 15th century, made its way to Spain thanks to the discoveries of the Spanish conquerors. And there, corn suitable for the Mediterranean climate was adopted and grown. Because this Mediterranean climate was located in a similar place to the continental climate of the northeastern and midwestern United States, it soon flowed into the North American continent at the hands of British Puritan immigrants."

  The professor paused for a moment, and drew the graph. He drew the ratio of British peasantry to industrial worker next to the word 'British industrial structure.' .. From the 16th to the 17th centuries, more and more immigrants were moving to England. Then, as the population fled from the 1700s to 1750s, food began to overflow. There was no longer a need for many farmers. For this reason, the landlords eliminated the farmers who had been hoarding wheat in the fields and instead began raising sheep to produce wool

  The professor largely erased the percentage of farmers from the graph. "When the percentage of farmers in industrial groups decreased in this way, the number of industrial workers increased significantly. As a result, the first industrial revolution took place in England." This time, the professor turned to the United States. "In the United States, the British Industrial Revolution shifted, but it was the driving force behind the Second Industrial Revolution. The borders that spanned the Midwest were erased at the end of the American-Mexico War, which began in 1848, and as a result of the elimination of borders and disputes in the Midwest, farmers planted corn as they pleased, and the corn belt was formed in the 1850s. As a result, the industrial revolution revolved around the Midwest and the Northern part of the United States. At this time, Germany also experienced the Second Industrial Revolution as the population of Germany, which was in severe civil war, fled to the Midwest of the United States."

  The professor circled the United States in chalk and China in circles. "As I mentioned, the United States is a country that can produce food similar to China's. However, the United States, which began farming 300 years ago and less than 150 years ago in the Midwest, has more corn yields than people can currently feed on, unlike China, which has been farming for the past 2000 years. Indeed, there is an unprecedented amount of food left in human history."

  The professor connected the world by drawing lines, this time in England, Europe, and the United States. "The Western powers of Europe and the United States spread all over the world at the start of the Industrial Revolution. China, India, Africa, and South America were of extraordinary size, unlike small Western European countries such as Britain, France, Spain, and Germany. Immigration to the United States did not result in a significant reduction in population size. Rather, the world was connected with surplus food produced in the Midwest of the United States."

  This time, the professor drew a graph next to India on a world map and wrote, "Indian industrial structure." "The leftover food from the United States was exported to Africa, India, China, and South America. And the rest of the world, which imported food from the West, grew in population as food suddenly increased. As a result, their local populations began to surpass the amount of food they produced locally. The industrial structure began to change."

  The professor greatly increased the graph of farmers in India's industrial structure to chalk and reduced the proportion of industrial workers. "It started out small. India, the world's most famous textile manufacturing base at the time, began to receive cheap Western food from its factory workers after being taken over by Britain. As a result, workers who could afford to buy cheap food and live on household budgets had many children. Eventually, the children became too many to feed working in factories. As a result, they went back to work as farmers to feed the children. India's textile industry, which it boasted, ended up in failure. This is why the world is now lagging behind the West."

  He picked up red chalk this time, and connected it to Europe and China by drawing lines from China, India, Africa, and South America. "…but now the trend has been reversed. Countries all over the world that have been impoverished by the West are migrating to Western societies. And as a result, there's a virtuous cycle of fewer food being exported from Western societies to the rest of the world, and then global population growth is decreasing." The professor picked up the chalk and placed it on his index finger, balancing both sides. "One day, human food self-sufficiency will be the same. Their finance, their populations... will eventually be perfectly balanced, as is as it should be in the natural state."
