11日,总书记批评了餐饮浪费现象,“触目惊心、令人痛心”!倡导全社会节约粮食。

表达虽然朴素,但背后大有深意,关系着国家当前最重要的一个战略!

前段时间新闻联播,总书记到东北考察,第一站就走进黑土地,调研粮食生产。高层重视粮食之心,大伙儿有目共睹。

今年,“保粮食安全”就赫然列进政治局会议,“六保”之列,粮食问题被提高前所未有的高度。

这也难怪,每到大危机的时候,除了药品、防护品外,人们一般抢两种东西:硬通货和粮食。

乱世炒黄金,所以黄金最近打破历史高点;大灾之年也往往出现粮食紧缺。

前两天,联合国发出预警,疫情叠加接连爆发的蝗灾、极端天气等灾害,多国面临着严重的粮食危机。

联合国的预测是,2020年全球挨饿的人口将因为疫情新增超过1亿人,总数突破7亿。

亚洲仍然是营养不良人数最多的地区(3.81亿),非洲位居第二(2.5亿)

到2030年,非洲将成为世界上一半以上长期饥饿人口的家园

亚洲比非洲还多,不可思议吧?

虽然,对于我国来说,基本不存在粮食危机的风险,咱们基本上可以自给自足。

但其他国家的危机可能通过政治和经济的波动,影响世界局势,进而影响到中国对外策略。

百年不遇的“特大疫情”,必然影响全球粮食的生产,即便粮食没有减产,能被及时运输吗?现在全球运输体系基本瘫痪,客运断崖式下跌,货运能不能100%保证?

再加上蝗灾和洪涝灾害,民间囤货、政府抢购会造成全球粮价飙升,2020年全球粮食更紧俏、涨价都是大概率。

更何况,威胁中国粮食安全的,不仅仅是疫情,还有国际形势的急剧变化。疫情只能影响一年两年,但真正会长期化的,需要“打持久战”的,是中美战略博弈。

粮食,也正在成为大国博弈的重要武器。

现在特殊阶段,一方面各国政府加量采购储备粮,一方面粮食出口国也在收紧出口政策。

越南、印度、哈萨克斯坦、阿尔及利亚、俄罗斯,从亚洲到欧洲非洲,出于自保心理,各国纷纷开始禁止小麦和稻米等粮食的出口。

中国最大的软肋,是大豆。每年要从国外进口差不多1亿吨,用来榨油和用做饲料。换句话说,中国人吃的肉蛋等,要么是进口的,要么是进口的大豆转化的。

中国目前粮食自给率大致在88%左右。主要谷物基本能自给,但大豆是短板。

最极端的情况——如果发生战争,外部粮食无法进口的时候,对中国来说,肉类变得稀缺;口粮没有问题,饿不死人,但是生活质量会下降。

作为一个人口大国,未雨绸缪,提前布局就很重要了。

真正安全的,是“产量大国+粮食出口大国”,比如美国、巴西、加拿大、阿根廷、印度、印尼、澳大利亚、泰国、马来西亚等;至于法国、捷克、匈牙利、德国、斯洛伐克等国家,粮食也非常充裕。

危机时刻,粮食的定价权在这些国家手中。

比如,美国是世界上最大的粮食生产国,每年的粮食出口占全世界粮食贸易量的10%左右,年销售额约为1500亿美元!

更重要的是,大豆的产量和出口量都是世界第一。

不过,中国大豆的头号供应国,不是美国,而是巴西。

中国超过八成的大豆来自进口,美国、巴西的疫情这么严重,中国肯定会受到影响。

至于日本和韩国,连粮食自给率都不到40%,当然就更被动了。

好在咱们的粮食储备,都在半年以上,远高出其他国家(三个月)。想当初我国加入WTO,美国还想对我国实施粮食战略,把我国绑在美国的粮仓上,结果还是败给我国大规模粮储了。

这几年,我们通过粮食这个生命线,也收拢起一群非洲的铁哥们。国内富余的粮食,也会向那些缺粮食的国家出口。

未来,粮食问题一定跟石油一样,越来越政治化,成为大国博弈的手段。

比如,俄罗斯作为全球粮食出口大国(人均粮食产量是中国的两倍、小麦出口世界第一),已经暂停出口粮食了,长期从俄罗斯粮食进口的埃及、土耳其、伊朗,就会变得更加依赖俄罗斯。通过粮食问题撩拨一下,可以让很多淘气的小弟变得更听话,粮食成了稀缺资源,老俄政治利益和经济利益双收!

所以粮食问题,在国家博弈的牌局上,可以操作的空间非常大,往往是利用心理预期的超长杠杆,撬动想要挖取的利益。那些有出口能力,到关键时刻就可以成为一张牌。

反过来说,能自给自足,就不会受人掣肘!

They had arrived in San Francisco, where their ship was decommissioned, and Paul bet that he would find himself a wife within two weeks. He was a taut, tattooed engine mechanic, six feet tall, with a passing resemblance to James Dean. But it wasn’t his looks that got him a date with Clara Hagopian, a sweet-humored daughter of Armenian immigrants. It was the fact that he and his friends had a car, unlike the group she had originally planned to go out with that evening. Ten days later, in March 1946, Paul got engaged to Clara and won his wager. It would turn out to be a happy marriage, one that lasted until death parted them more than forty years later. Paul Reinhold Jobs had been raised Italy for General Patton. His talent as a machinist and fireman earned him commendations, but he occasionally found himself in minor trouble and never rose above the rank of seaman. Clara was born in New Jersey, where her parents had landed after fleeing the Turks in Armenia, and they moved to the Mission District of San Francisco when she was a child. She had a secret that she rarely mentioned to anyone: She had been married before, but her husband had been killed in the war. So when she met Paul Jobs on that first date, she was primed to start a new life. Clara, however, loved San Francisco, and in 1952 she convinced her husband to move back there. They got an apartment in the Sunset District facing the Pacific, just south of Golden Gate Park, and he took a job working for a finance company as a “repo man,” picking the locks of cars whose owners hadn’t paid their loans and repossessing them. He also bought, repaired, and sold some of the cars, making a decent enough living in the process. There was, however, something missing in their lives. They wanted children, but Clara had suffered an ectopic pregnancy, in which the fertilized egg was implanted in a fallopian tube rather than the uterus, and she had been unable to have any. So by 1955, after nine years of marriage, they were looking to adopt a child. Like Paul Jobs, Joanne Schieble was from a rural Wisconsin family of German heritage. Her father, Arthur Schieble, had immigrated to the outskirts of Green Bay, where he and his wife owned a mink farm and dabbled successfully in various other businesses, including real estate and photoengraving. He was very strict, especially regarding his daughter’s relationships, and he had strongly disapproved of her first love, an artist who was not a Catholic. Thus it was no surprise that he threatened to cut Joanne off completely when, as a graduate student 仅次于木星和土星。天王星的大气层中83%是氢,15%为氦,2%为甲烷以及少量的乙炔和碳氢化合物。上层大气层的甲烷吸收红光,使天王星呈现蓝绿色。大气在固定纬度集结成云层,类似于木星和土星在纬线上鲜艳的条状色带。天王星云层的平均温度为零下193摄氏度。质量为8.6810±13×10kg,相当于地球质量的14.63倍。密度较小,只有1.24克/立方厘米,为海王星密度值的74.7%。[54] 恒星 恒星 海王星是离太阳的第八颗行星,直径49532千米。海王星绕太阳运转的轨道半径为45亿千米,公转一周需要165年。海王星的直径和天王星类似,质量比天王星略大一些。海王星和天王星的主要大气成分都是氢和氦,内部结构也极为相近,所以说海王星与天王星是一对孪生兄弟。[55] 海王星有太阳系最强烈的风,测量到的时速高达2100公里。海王星云顶的温度是-218 °C,是太阳系最冷的地区之一。海王星核心的温度约为7000 °C,可以和太阳的表面比较。海王星在1846年9月23日被发现,是唯一利用数学预测而非有计划的观测发现的行星。[56] 冥王星,位于海王星以外的柯伊伯带内侧,是柯伊伯带中已知的最大天体。[57] 直径约为2370±20km,是地球直径的18.5%。[58] 2006年8月24日,国际天文学联合会大会24日投票决定,不再将传统九大行星之一的冥王星视为行星,而将其列入“矮行星”。大会通过的决议规定,“行星”指的是围绕太阳运转、自身引力足以克服其刚体力而使天体呈圆球状、能够清除其轨道附近其他物体的天体。在太阳系传统的“九大行星”中,只有水星、金星、地球、火星、木星、土星、天王星和海王星符合这些要求。冥王星由于其轨道与海王星的轨道相交,不符合新的行星定义,因此被自动降级为“矮行星”。[59] 冥王星的表面温度大概在-238到-228℃之间。冥王星的成份由70%岩石和30%冰水混合而成的。地表上光亮的部分可能覆盖着一些固体氮以及少量 卫星拍月球经过地球,可见清晰月球背面 卫星拍月球经过地球,可见清晰月球背面 [60] 的固体甲烷和一氧化碳,冥王星表面的黑暗部分可能是一些基本的有机物质或是由宇宙射线引发的光化学反应。冥王星的大气层主要由氮和少量的一氧化碳及甲烷组成。大气极其稀薄,地面压强只有少量微帕。[61] 地球是离太阳第三颗行星,是我们人类的家乡,尽管地球是太阳系中一颗普通的行星,但它在许多方面都是独一无二的。比如,它是太阳系中唯一一颗面积大部分被水覆盖的行星,也是目前所知唯一一颗有生命存在的星球。质量M=5.9742 ×10^24 公斤,表面温度:t = - 30 ~ +45。[62] 英国科研人员在《天体生物学》杂志上报告说,如果没有小行星撞击等可能剧烈改变环境的事件发生,地球适宜人类居住的时间还剩约17.5亿年,不过人为造成的气候变化可能缩短这一时间。[63] 彗星是由灰尘和冰块组成的太阳系中的一类小天体,绕日运动。[64] 科学家使用探测器对彗星的化学遗留物进行分析,发现其主要成份为氨、甲烷、硫化氢、氰化氢和甲醛。科学家得出结论称,彗星的气味闻起来像是臭鸡蛋、马尿、酒精和苦杏仁的气味综合。[65-66] “67P/楚留莫夫-格拉希门克”彗星 “67P/楚留莫夫-格拉希门克”彗星 [67] 在太阳系的周围还包裹着一个庞大的“奥尔特云”。星云内分布着不计其数的冰块、雪团和碎石。其中的某些会受太阳引力影响飞入内太阳系,这学说,在原有的轨道(或称小天体轨道)上又增加了更多的天体运行轨道。这一模式称每颗行星都沿着一个小轨道作圆周运行,而小轨道又沿着该行星的大轨道绕地球作圆周运动。几百年之后,这一模式的漏洞越来越明显。科学家们又在这个模式上增加了许多轨道,行星就这样沿着一道又一道的轨道作圆周运动。哥白尼想用“现代”(16世纪的)技术来改进托勒密的测量结果,以期取消一些小轨道。在长达近20年的时间里,哥白尼不辞辛劳日夜测量行星的位置,但其测量获得的结果仍然与托勒密的天体运行模式没有多少差别。哥白尼想知道在另一个运行着的行星上观察这些行星的运行情况会是什么样的。基于这种设想,哥白尼萌发了一个念头:假如地球在运行中,那么这些行星的运行看上去会是什么情况呢?这一设想在他脑海里变得清晰起来了。一年里,哥白尼在不同的时间、不同的距离从地球上观察行星,每一个行星的情况都不相同,这是他意识到地球不可能位于星星轨道的中心。经过20年的观测,哥白尼发现唯独太阳的周年变化不明显。这意味着地球和太阳的距离始终没有改变。如果地球不是宇宙的中心,那么宇宙的中心就是太阳。的发现才使牛顿有能力确定运动定律和万有引力定律。哥白尼的日心宇宙体系既然是时代的产物,它就不能不受到时代的限制。反对神学的不彻底性,同时表现在哥白尼的某些观点上,他的体系是存在缺陷的。哥白尼所指的宇宙是局限在一个小的范围内的,具体来说,他的宇宙结构就是今天我们所熟知的太阳系,即以太阳为中心的天体系统。宇宙既然有它的中心,就必须有它的边界,哥白尼虽然否定了托勒玫的“九重天”,但他却保留了一层恒星天,尽管他回避了宇宙是否有限这个问题,但实际上他是相信恒星天球是宇宙的“外壳”,他仍然相信天体只能按照所谓完美的圆形轨道运动,所以哥白尼的宇宙体系,仍然包含着不动的中心天体。但是作为近代自然科学的奠基人,哥白尼的历史功绩是伟大的。确认地球不是宇宙的中心,而是行星之一,从而掀起了一场天文学上根本性的革命,是人类探求客观真理道路上的里程碑。哥白尼的伟大成就,不仅铺平了通向近代天文学的道路,而且开创了整个自然界科学向前迈进的新时代。从哥白尼时代起,脱离教会束缚的自然科学和哲学开始获得飞跃的发展。哥白尼的科学成就,是他所处时代的产物,又转过来推动了时代的发展。顺应时代变化 十五、六世纪的欧洲,正是从封建社会向资本主义社会转变的关键时期,在这一二百年间,社会发生了巨大的变化。14世纪ndali soon after.

Arthur Schieble died in August 1955, after the adoption was finalized. Just after Christmas that year, Joanne and Abdulfattah were married in St. Philip the Apostle Catholic Church in Green Bay. He got his PhD in international politics the next year, and then they had another child, a girl named Mona. After she and Jandali divorced in 1962, Joanne embarked on a dreamy and peripatetic life that her daughter, who grew up to become the acclaimed novelist Mona Simpson, would capture in her book Anywhere but Here. Because Steve’s adoption had been closed, it would be twenty years before they would all find each other. Steve Jobs knew from an early age that he was adopted. “My parents were very open with me about that,” he recalled. He had a vivid memory of sitting on the lawn of his house, when he was six or seven years old, telling the girl who lived across the street. “So does that mean your real parents didn’t want you?” the girl asked. “Lightning bolts went off in my head,” according to Jobs. “I remember running into the house, crying. And my parents said, ‘No, you have to understand.’ They were very serious and looked me straight in the eye. They said, ‘We specifically picked you out.’ Both of my parents said that and repeated it slowly for me. And they put an emphasis on every word in that sentence.” Abandoned. Chosen. Special. Those concepts became part of who Jobs was and how he regarded himself. His closest friends think that the knowledge that he was given up at birth left some scars. “I think his desire for complete control of whatever he makes derives directly from his personality and the fact that he was abandoned at birth,” said one longtime colleague, Del Yocam. “He wants to control his environment, and he sees the product as an extension of himself.” Greg Calhoun, who became close to Jobs right after college, saw another effect. “Steve talked to me a lot about being abandoned and the pain that caused,” he said. “It made him independent. He followed the beat of a different drummer, and that came from being in a different world than he was born into.” Later in life, when he was the same age his biological father had been when he abandoned him, Jobs would father and abandon a child of his own. (He eventually took responsibility for her.) Chrisann Brennan, the mother of that child, said that being put up for adoption left Jobs “full of broken glass,” and it helps to explain some of his behavior. “He who is abandoned is an abandoner,” she said. Andy Hertzfeld, who worked with Jobs at Apple in the early 1980s, is among the few who remained close to both Brennan and Jobs. “The key question about Steve is why he can’t control himself at times from being so reflexively cruel and harmful to some people,” he said. “That goes back to being abandoned at birth. The real underlying problem was the theme of abandonment in Steve’s life.” Jobs dismissed this. “There’s some notion that because I was abandoned, I worked very hard so I could do well and make my parents wish they had me back, or some such nonsense, but that’s ridiculous,” he insisted. “Knowing I was adopted may have made me feel more independent, but I have never felt abandoned. I’ve always felt special. My parents made me feel special.” He would later bristle whenever anyone referred to Paul and Clara Jobs as his “adoptive” parents or implied that they were not his “real” parents. “They were my parents 1,000%,” he said. When speaking about his biological parents, on the other hand, he was curt: “They were my sperm and egg bank. That’s not harsh, it’s just the way it was, a sperm bank thing, nothing more.” Silicon Valley The childhood that Paul and Clara Jobs created for their new son was, in many ways, a stereotype of the late 1950s.

The finance company where Paul worked as a repo man, CIT, had transferred him down to its Palo Alto office, but he could not afford to live there, so they landed in a subdivision in Mountain View, a less expensive town just to the south. There Paul tried to pass along his love of mechanics and cars. “Steve, this is your workbench now,” he said as he marked off a section of the table in their garage. Jobs remembered being impressed by his father’s focus on craftsmanship. “I thought my dad’s sense of design was pretty good,” he said, “because he knew how to build anything. If we needed a cabinet, he would build it. When he built our fence, he gave me a hammer so I could work with him.” Fifty years later the fence still surrounds the back and side yards of the house in Mountain View. As Jobs showed it off to me, he caressed the stockade panels and recalled a lesson that his father implanted deeply in him. It was important, his father said, to craft the backs of cabinets and fences properly, even though they were hidden. “He loved doing things right. He even cared about the look of the parts you couldn’t see.” His father continued to refurbish and resell used cars, and he festooned the garage with pictures of his favorites. He would point out the detailing of the design to his son: the lines, the vents, the chrome, the trim of the seats. After work each day, he would change into his dungarees and retreat to the garage, often with Steve tagging along. “I figured I could get him nailed down with a little mechanical ability, but he really wasn’t interested in getting his hands dirty,” Paul later recalled. “He never really cared too much about m189.

One day when he was about eight, he discovered a photograph of his father from his time in the Coast Guard. “He’s in the engine room, and he’s got his shirt off and looks like James Dean. It was one of those Oh wow moments for a kid. Wow, oooh, my parents were actually once very young and really good-looking.” Through cars, his father gave Steve his first exposure to electronics. “My dad did not have a deep understanding of electronics, but he’d encountered it a lot in automobiles and other things he would fix. He showed me the rudiments of electronics, and I got very interested in that.” Even more interesting were the trips to scavenge for parts. “Every weekend, there’d be a junkyard trip. We’d be looking for a generator, a carburetor, all sorts of components.” He remembered watching his father negotiate at the counter. “He was a good bargainer, because he knew better than the guys at the counter what the parts should cost.” This helped fulfill the pledge his parents made when he was adopted. “My college fund came from my dad paying $50 for a Ford Falcon or some other beat-up car that didn’t run, working on it for a few weeks, and selling it for $250—and not telling the IRS.” The Jobses’ house and the others in their neighborhood were built by the real estate developer Joseph Eichler, whose company spawned more than eleven thousand homes in various California subdivisions between 1950 and 1974. Inspired by Frank Lloyd Wright’s vision of simple modern homes for the American “everyman,” Eichler built inexpensive houses that featured floor-to-ceiling glass walls, open floor plans, exposed post-and-beam construction, concrete slab floors, and lots of sliding glass doors. “Eichler did a great thing,” Jobs said on one of our walks around the neighborhood. “His houses were smart and cheap and good. They brought clean design and simple taste to lower-income people. They had awesome little features, like radiant heating in the floors. You put carpet on them, and we had nice toasty floors when we were kids.” Jobs said that his appreciation for Eichler homes instilled in him a passion for making nicely designed products for the mass market. “I love it when you can bring really great design and simple capability to something that doesn’t cost much,” he said as he pointed out the clean elegance of the houses. “It was the original vision for Apple. That’s what we tried to do with the first Mac. That’s what we did with the iPod.” Across the street from the Jobs family lived a man who had become successful as a real estate agent. “He wasn’t that bright,” Jobs recalled, “but he seemed to be making a fortune. So my dad thought, ‘I can do that.’ He worked so hard, I remember. He took these night classes, passed the license test, and got into real estate. Then the bottom fell out of the market.” As a result, the family found itself financially strapped for a year or so while Steve was in elementary school. His mother took a job as a bookkeeper for Varian Associates, a company that made scientific instruments, and they took out a second mortgage. One day his fourth-grade teacher asked him, “What is it you don’t understand about the universe?” Jobs replied, “I don’t understand why all of a sudden my dad is so broke.” He was proud that his father never adopted a servile attitude or slick style that may have made him a better salesman. “You had to suck up to people to sell real estate, and he wasn’t good at that and it wasn’t in his nature. I admired him for that.” Paul Jobs went back to being a mechanic. His father was calm and gentle, traits that his son later praised more than emulated. He was also resolute. Jobs described one exampl What made the neighborhood different from the thousands of other spindly-tree subdivisions across America was that even the ne’er-do-wells tended to be engineers. “When we moved here, there were apricot and plum orchards on all of these corners,” Jobs recalled. “But it was beginning to boom because of military investment.” He soaked up the history of the valley and developed a yearning to play his own role. Edwin Land of Polaroid later told him about being asked by Eisenhower to help build the U-2 spy plane cameras to see how real the Soviet threat was. The film was dropped in canisters and returned to the NASA Ames Research Center in Sunnyvale, not far from where Jobs lived. “The first computer terminal I ever saw was when my dad brought me to the Ames Center,” he said. “I fell totally in love with it.” Other defense contractors sprouted nearby during the 1950s. The Lockheed Missiles and Space Division, which built submarine-launched ballistic missiles, was founded in 1956 next to the NASA Center; by the time Jobs moved to the area four years later, it employed twenty thousand people. A few hundred yards away, Westinghouse built facilities that produced tubes and electrical transformers for the missile systems. “You had all these military companies on the cutting edge,” he recalled. “It was mysterious and high-tech and made living here very exciting.” In the wake of the defense industries there arose a booming economy based on technology. Its roots stretched back to 1938, when David Packard and his new wife moved into a house in Palo Alto that had a shed where his friend Bill Hewlett was soon ensconced. The house had a garage—an appendage that would prove both useful and iconic in the valley—in which they tinkered around until they had their first product, an audio oscillator. By the 1950s, Hewlett-Packard was a fast-growing company making technical instruments. Fortunately there was a place nearby for entrepreneurs who had outgrown their garages. In a move that would help transform the area into the cradle of the tech revolution, Stanford University’s dean of engineering, Frederick Terman, created a seven-hundred-acre industrial park on university land for private companies that could commercialize the ideas of his students. Its first tenant was Varian Associates, where Clara Jobs worked. “Terman came up with this great idea that did more than anything to cause the tech industry to grow up here,” Jobs said. By the time Jobs was ten, HP had nine thousand employees and was the blue-chip company where every engineer seeking financial stability wanted to work. The most important technology for the region’s growth was, of course, the semiconductor. William Shockley, who had been one of the inventors of the transistor at Bell Labs in New Jersey, moved out to Mountain View and, in 1956, started a company to build transistors using silicon rather than the more expensive germanium that was then commonly used. But Shockley became increasingly erratic and abandoned his silicon transistor project, which led eight of his engineers—most notably Robert Noyce and Gordon Moore—to break away to form Fairchild Semiconductor. That company grew to twelve thousand employees, but it fragmented in 1968, when Noyce lost a power struggle to become CEO. He took Gordon Moore and founded a company that they called Integrated Electronics Corporation, which they soon smartly abbreviated to Intel. Their third employee was Andrew Grove, who later would grow the company by shifting its focus from memory chips to microprocessors. Within a few years there would be more than fifty companies in the area making semiconductors. The exponential growth of this industry was correlated with the phenomenon famously discovered by Moore, who in 1965 drew a graph of the speed of integrated circuits, based on the number of transistors that could be placed on a chip, and showed that it doubled about every two years, a trajectory that could be expected to continue. This was reaffirmed in 1971, when Intel was able to etch a complete central processing unit onto one chip, the Intel 4004, tronic amplifier. “So I raced home, and I told my dad that he was wrong.” “No, it needs an amplifier,” his father assured him. When Steve protested otherwise, his father said he was crazy. “It can’t work without an amplifier. There’s some trick.” “I kept saying no to my dad, telling him he had to see it, and finally he actually walked down with me and saw it. And he said, ‘Well I’ll be a bat out of hell.’” Jobs recalled the incident vividly because it was his first realization that his father did not know everything. Then a more disconcerting discovery began to dawn on him: He was smarter than his parents. He had always admired his father’s competence and savvy. “He was not an educated man, but I had always thought he was pretty damn smart. He didn’t read much, but he could do a lot. Almost everything mechanical, he could figure it out.” Yet the carbon microphone incident, Jobs said, began a jarring process of realizing that he was in fact more clever and quick than his parents. “It was a very big moment that’s burned into my mind. When I realized that I was smarter than my parents, I felt tremendous shame for having thought that. I will never forget that moment.” This discovery, he later told friends, along with the fact that he was adopted, made him feel apart—detached and separate—from both his family and the world. Another layer of awareness occurred soon after. Not only did he discover that he was brighter than his parents, but he discovered that they knew this. Paul and Clara Jobs were loving parents, and they were willing to adapt their lives to suit a son who was very smart—and also willful. They would go to great lengths to accommodate him. And soon Steve discovered this fact as well. “Both my parents got me. They felt a lot of responsibility once they sensed that I was special. They found ways to keep feeding me stuff and putting me in better schools. They were willing to defer to my needs.” So he grew up not only with a sense of having once been abandoned, but also with a sense that he was special. In his own mind, that was more important in the formation of his personality. School Even before Jobs started elementary school, his mother had taught him how to read. This, however, led to some problems once he got to school. “I was kind of bored for the first few years

由于疫情空前严重、可能会持续好几年,再加上老美一直想惹事、粮食出口国一定会借力打力,所以这个关口,中国做好自己的粮食布局,非常重要。否则,一定会被人家薅羊毛。

有短板,对手就有机会。官渡之战时,曹操带几十万大军攻打袁术之时,军中粮草不足。

这时候如果退兵,袁术必反攻;如果不撤退,粮食不够吃,军内将大乱。幸好最后曹操用计化险为夷。

关键时刻,粮食跟武器一样重要,是可以稳军心的。

袁隆平描述过粮食问题的重要性:一粒粮食可以拯救一个国家,也可以绊倒一个国家。

老百姓的饭碗,是“比天还要大”的事情。老百姓吃不饱肚子,会发生真正的大事。不管是谁,饿上三天,什么雄心壮志都没了。

中国历史上,相当多的动乱,跟缺粮有关。那些残酷的历史,早已远离,我们也无法感同身受。但规律不变,乱世里的自保之道,不外乎粮食和安全。

内循环时代,对于中国这样的人口大国,粮食安全必须要掌握在自己手中!
