Not only do food, corn also fuel, is a genetics wonder of humanity; And also caused some left side for America.0: 00/4: 59 male in the US Department of Agriculture (USDA), more than 37 million hectares of agricultural land of the country are devoted to corn production.

. Corn becomes the main entertainment dish of the fall. The genetic story of the wilderness is not really created about 9,000 years ago through the selection of a Mexican grass called Teosinte . Geneticists have determined that farmers living in today's area of Mexico's Balsas River Valley must have seen potential food in thin and extremely hard teosinte particles, only a few seeds on the core Little corn
After thousands of years of efforts, indigenous farmers have tried to breed a beads that are not wrapped in hard shells, which are still intact when trying to separate seeds and can be easily planted Big scale. This is discovered by Christopher Columbus and introduces the world at the end of the 15th century. The final result is a crop not only does not exist in nature but cannot exist in nature. As Indiana Public Media wrote in 2009, "All particles are tightened on the core and wrapped tightly inside the thick shell. It seems that the seed cannot be disperse without people with peeling and separating" . However, despite these fertility disadvantages, there are six types of corn grown in the United States today: concave corn, usually yellow, with concave seeds and used in products such as animal feed, Wine, chips and corn cakes; Corn stone, with lots of corn seeds and can be used to bake, popcorn or decorate; sweet corn, have a slightly yellow and white and edible color; corn powder, used to make corn flour; Corn explosion, can be corn ice and any species exploded when heated; And corn shells, grow leaves around each particle and are not grown for commercial purposes, but are used in some native American religious rituals. In addition, corn is also used to create ethanol, Fuel for vehicles from cars to missile ships; such as dextrin compounds, can be used to produce adhesives, soaps, insulation materials, straws and inks; such as corn syrup, used in finishing textiles, shoe polish and makeup stage; And in the form of corn starch, used in rubber tires, insecticides and dry batteries. According to the US Agricultural Ministry (USDA), more than 37 million hectares of agricultural land of the country are reserved for production Pouring corn. With countless uses from corn trees, this is not surprisingly. The opposite of the dominance of NgoTy, having such large areas that are fully spent on a single crop causing these crops Significant environmental damage
First, because corn and soybeans have become two main crops in the US, the diversity of plant species has fallen sharply. This makes the US food supplies more vulnerable to any external crisis that can interrupt production, such as pests or harsh weather phenomena. Because of the industry Corn career receives more government subsidies than any other crops (including $ 90 billion from 1995 to 2010), it is extremely expensive for taxpayers. Because they cause waste of land when they can use land more diverse. Or all fertilizers and pesticides used to maintain these huge corn cases will definitely run out of water supply or become polluted. People eat many corn as today in the diet Nor good for health. For example, corn syrup with high fructose content is a sweetener made from corn starch found in everything, from candy and fresh water to fast food and spices. This product is also related to the risk of obesity, fatty liver disease, cardiovascular disease, diabetes and even higher cancer. American dependence on corn is also called a national security risk . When President Donald Trump increased taxes on Chinese and Chinese products to respond by increasing tax rates for some US imported products, the corn industry needs Washington's relief packages to maintain operations. . A significant portion of US corn harvested abroad, and this became a security vulnerability.Erl Butz, once the US agricultural minister under President Richard Nixon and Gerald Ford, considered a fairy Phong in the modern American corn policy because he emphasized the sale of foreign abroad and producing in large quantities. This makes corn prices fall and encourage businesses to find new creative methods to use this unexpectedly cheap nuts. Logo and climate generals, access to food has difficulties once the supply chain is Breaking due to harsh weather phenomena, but the corn industry will be particularly vulnerable to h . Dịch vụ:
