Why can’t Africa develop?

Question 1: Why has Africa never developed? 1. The slave trade has caused Africa to lose nearly 100 million hardcover labor force, which is the historical root cause of poverty in Africa

2. All countries and all races The long-term war has prevented economic development.

3. Overpopulation damages the environment

4. Africa mostly has a tropical climate, which is not conducive to agricultural development.

5. The massive loss of talent and the backwardness of technology are also the most important reasons.

Question 2: Why can’t Africa develop? Rough sketch of logical thinking

A woman asked God: “Why did he create man first and then woman?”

God Answer: "Before any perfect work is born, there will be a rough sketch."

Question 3: What is the reason why Africa cannot develop? Africa is still the poorest region in the world. The root causes of the problem are multifaceted, but low technological level is undoubtedly one of the important factors. The African economy is highly dependent on the export of low value-added primary products. One of the reasons is that many African countries are backward in science and technology, have weak processing capabilities, and have low product processing ratios and low processing levels. For example, since most local African mining companies do not have deep processing capabilities and export only primary products with very low added value, despite the huge export volume of African mineral products, their contribution to the regional economy is very limited. Africa has the lowest grain yield per unit area in the world, due to backward grain production technology and primitive production methods. Some experts pointed out that Africa is in great need of biotechnology, because biotechnology can increase the production and nutritional content of African food, thereby solving problems such as hunger and malnutrition among Africans. As mankind enters the information age, some ordinary communication and information products are still luxuries in sub-Saharan Africa, and some villages are still "isolated" from the rest of the world. In this region, there are only 31.6 telephones and 9.2 computers per 1,000 people. Due to weak infrastructure and lack of hardware equipment, the cost of Internet access in this region is much higher than that in other parts of the world, almost 10 times that of the United States. Although Africa ambitiously proposed an information society plan in 1996, due to various objective constraints, Africa's information technology development level still lags behind other regions in the world. Brain drain affects scientific and technological progress. There are many reasons why Africa is lagging behind in science and technology. Serious brain drain and insufficient investment in R&D funds are two main aspects. Currently, the number of African scientists and engineers only accounts for 0.36% of the world's total. However, on average, more than 20,000 university graduates from Africa go to developed countries in Europe and the United States every year, and many of them "never return." So far, more than 600,000 African technicians are working in developed countries, including scientists, doctors and engineers, and more than 40,000 of them have doctorates. Each African scientific and technological talent who immigrated to developed countries in Europe and the United States takes away an average of about US$184,000 in training fees, which is enough to support 500 farmers in the least developed countries in Africa for one year. At the same time, in order to make up for the lack of talent, African countries have to hire foreign experts at high salaries. The annual cost of paying the salaries of foreign experts reaches more than 4 billion U.S. dollars. This alone consumes half of the foreign aid funds Africa receives every year. one third. Low income and insufficient scientific research funding are the main reasons for brain drain in Africa. The top priority of most African countries is to solve the problem of feeding their citizens, and the funds for scientific and technological development and attracting talents are very limited. Investment in science and technology in Africa except South Africa only accounts for 0.2% of the gross national product. Brain drain has weakened Africa's economic development momentum and competitiveness, and the wisdom of Africans has not been fully applied to Africa's economic development. Many African researchers are working for European and American pharmaceutical companies, but many people in Africa die every day due to lack of medical treatment; when some African countries are racking their brains to design a small hydropower station, famous scientists from Mali, West Africa, are Diarra is already participating in the US Mars exploration program.

Question 4: Please explain in detail why Africa has not been able to develop for so long. After hundreds of years of colonial rule, the economy is mostly a single commodity economy

Question 5: Why can’t black African countries develop? They have no money, are not suitable for developing agriculture, have a weak industrial base, and have a very low cultural level of their people.

Question 6: Why do most African countries fail to develop? This is because they lag behind other developing countries in terms of population, climate, cultural level and technology.

Question 7: China has developed, but why has Africa not changed much? The 15-year protective transition period for China to join the WTO has ended. Think about what has happened to China in the past 15 years. And what about Africa?

Question 8: Why can’t agriculture develop in Africa? First, it’s because of climate. Africa’s large areas of deserts and grasslands have little or too concentrated rainfall, and the ecology is fragile, making them unsuitable for agricultural development. Second, it’s because of technology. , Africa’s traditional agriculture has a weak foundation, very backward technology, and very underdeveloped agriculture.

Question 9: Why can’t urban residents in Africa get rich because they are backward?

Question 10: Why did humans originate in Africa, but modern civilization developed in Europe 1. Each continent can Domesticated animals and plants are different. Eurasia has more animals and plants that can be used by humans, while large animals in Australia and the Americas are more difficult to domesticate and cannot be used as livestock to feed many people.

2. The rate of spread of technology and plants and animals differs within different continents. Eurasia runs east-west, and animals and plants spread more easily across the same latitudes (this is easy to understand, after all, taking penguins to the tropics will kill them from the heat). Eurasia is not only the main axis in the east-west direction, but also has no tall and long mountain ranges blocking the spread of east-west direction (due to the existence of the Himalayas, where India and several surrounding countries are located, we usually call it the Indian subcontinent). The African continent has a main north-south axis. Because of the different climates at different latitudes, there will be some obstacles to the spread of animals and plants. The American continent is not only the main axis in the north-south direction, but also has many tall mountains that block the spread of animals and plants (the Andes). The North and South American continents are only connected by Panama, and they are almost completely disconnected continents.

3. Technology and plants and animals spread at different rates across continents. The African continent and Eurasia are connected together, so most of the livestock in sub-Saharan Africa come from Eurasia. Because the Australian continent is far away from other continents, large mammals other than kangaroos appeared very late.

4. Population density varies across continents. A larger area or a larger population means more potential inventions and more competition. Because if you don’t adopt advantageous inventions, you are likely to be eliminated by your competitors. The competition between the American continent and the Eurasian continent is not as fierce as that of the Eurasian continent, so the early civilization development of the American continent is not as advanced as that of the Eurasian continent.

The above four arguments explain why human civilization originated in the Fertile Crescent (the Euphrates and Tigris river basins in Western Asia, Iraq and surrounding areas) and China. But it did not explain why Europe later surpassed Western Asia and China in terms of civilization. One reason for the gradual decline of the Fertile Crescent is that the local natural environment changed and the land gradually turned into a desert, so the center of civilization gradually moved westward, until today's Europe.
