The development of industrial civilization has improved human life, but at the same time deeply polluted land resources and harmed human health ...

According to the latest UN Annual Report on the State of Food Insecurity in the World 2015, the number of hungry people in the world is still 795 million, accounting for about one-ninth of the global population.

In the past 20 years, mankind invented pesticides and increased fertilizer production. At the same time, the use of industrial fertilizers has grown at an annual rate of 2.1% worldwide. Developed countries have set up 225 to prevent fertilizers from causing harm to soil and water bodies. The safe upper limit is kg / ha, and China has reached more than 400 kg / ha. At the same time, China has become the world's largest consumer of pesticides. The average amount of chemical pesticides per unit area is 2.5-5 times higher than the world average. The adverse consequences of excessive use of chemical fertilizers have also concentrated on the emergence of a triple crisis: water resources crisis, desertification, and ecological crisis.

In the industrialized agricultural system, it produces as much food as in the past, and now uses 10 times more water than in the past because agriculture has become a chemical-based agriculture; 75% of the soil has lost its fertility and is developing towards desertification. 21 million hectares of land are unable to grow cereals due to degradation. For example, the utilization rate of pesticides in China is less than 30%, of which 10% -20% is attached to plants, and the rest is scattered in the air, soil and water, which has caused great harm to soil, water sources, air and agricultural by-products. It has become a major problem facing China's food safety.

The United Nations has issued a warning that chemical agriculture is an important cause of very serious soil damage. Countless people are exploring and reflecting. Among them, Howard Buffett, the son of Warren Buffett, the god of shares, and his efforts in Africa may give this world some useful enlightenments.

成年后的霍华德度过了一段艰难时光,换过很多工作,好在最终还是找到了自己最喜欢的职业--农民。 Howard Buffett liked planting when he was very young, and even turned his backyard into a cornfield. As an adult, Howard had a difficult time and changed many jobs. Fortunately, he finally found his favorite job- Farmers. In 1986, with the help of the father of the stock god, Howard finally owned a piece of his own land, although he paid a lot of rent to his father every year.

However, Howard was an excellent farmer. With his careful management, the business of the farm was booming. A few years later, he succeeded in subleasing it at a high price. 刚开始从事慈善事业时,他在南非建立过猎豹保护区,资助过国际大猩猩保护计划,还亲身参与打击偷猎。 Perhaps the god of stock saw the son's commercial talent from the farm's operating conditions. Since then, Howard has gradually contacted the company's affairs. In the process, Howard not only accumulated business experience, but also accumulated personal wealth, and even established a charity named after him. The Foundation, when he started his philanthropy, established a cheetah sanctuary in South Africa, funded the International Gorilla Conservation Program, and personally participated in the fight against poaching. But shortly after, Howard realized that the best way to protect African wildlife is to improve the livelihoods of the locals.

"Living on the other side of the planet, it is easy to blame greedy poachers and corrupt government officials for destroying important ecosystems," he wrote in "40 Opportunities: Finding Hope in a Famine World", "but I also Seeing those who share the same ecosystem with endangered species are themselves endangered. Many people ca n’t eat enough ... I realize that we must change our focus and solve more fundamental problems. ”And the book“ 40 Opportunities ” The name comes from the peasant motto: You only have 40 years to cultivate the same land. What Howard wants to say is that one person has only 40 years to change the world.

In response to global hunger, especially the food problem in Africa, the "green revolution" plan given by many international organizations is "high yield wheat seeds, irrigation, large doses of fertilizers and pesticides that are resistant to pests and diseases." However, Howard believes that this model is not Suitable for sub-Saharan. This area is very wide and the terrain is diverse and requires diversified farming methods. Moreover, the civil war here for years, the government is incompetent and lacks infrastructure. To make matters worse, the quality of land in Africa is also deteriorating.

Howard said, "I am a farmer and I know the benefits of improving seeds. I know what fertilizers can create. They do have a significant effect, but they cannot create organic matter, they cannot create top soil, they cannot protect water quality. This is just an expedient, and Africa needs long-term solutions. "Rather than a green revolution, Howard advocates his" brown revolution "by promoting environmentally sustainable organic agriculture, reducing soil erosion, protecting renewable soil, and making land more resilient. Howard The Buffett Foundation has spent hundreds of millions of dollars to promote organic protective agriculture step by step: soil-covered crops, no-till cultivation, and local crop seed cultivation. Improve the quality of African soils and increase the output of agricultural products without the use of fertilizers and pesticides.

"In places like Africa," Howard said, "the soil is very bad, the nutrients are scarce, the land is almost squeezed out, to the point where farmers are forced to frequently switch places for farming. If your response is to throw it up Synthetic fertilizer is like putting an oxygen mask on a corpse and praying it will come back to life. "The Howard Fund now owns several high-tech experimental farms and employs a large number of agricultural experts from universities in the United States, specializing in soil and agriculture. Relationships to study how to grow crops by improving poor soil.
Howard said that farmers are the same all over the world, and we only focus on land. They found that during the cultivation process, as far as possible not to use chemicals such as fertilizers and pesticides, the organic matter in the soil would be restored faster, allowing microorganisms, earthworms and various insects to replace chemicals, providing nutrients to crops and restoring ecological diversity. It also has a significant role in minimizing human impact on the environment.

This is the perfect solution to the problem of hunger in Africa and the world.

Howard Buffett may not be alone, because more and more countries and groups realize that the situation of chemical fertilizer flooding must change. In the United States, in order to develop new and scientific organic breeding methods, organic farmers have invested a lot of money, resources and time, and even high scientific and technological research costs. They have also established the agricultural research service organization fAgriClllturalResearch Service, referred to as ARS. ) To solve the scientific and technological problems of helping farmers to obtain higher yields.

What kind of grass should be left in the field, what kind of bugs should be cultivated, and whether there should be a deep or shallow tillage, there is a complete set of solutions. In India, unlike the European and American developed countries, which promote the development and use of new technologies for organic farming, India's concept of organic agriculture is-retro! They use cow dung, raw seeds, and no chemical insect repellent. They are also looking for a solution that suits them. In Turkey, more and more farmers are engaged in organic agriculture. In order to be recognized by the international market, Turkish organic farms are certified according to the standards of exporting countries!

To this day, the main countries of Turkey's organic agricultural exports include EU countries, such as France, the United Kingdom, the Netherlands, Germany, Italy and so on. The market share of Turkish agricultural products in Switzerland, the United States, Belgium, Sweden, Elben, and South Korea is also expanding.

The issue of food safety has never left us, and the problem of chemical fertilizers cannot be avoided. Modern industry and agriculture can bring temporary high yields, but it will cause irreversible damage to the soil and the entire ecological environment. When some countries start working hard to change, and when some people start working hard, maybe we should also think about it, we can do something, China, we can do something!
