 Eat more meat to harm the environment? Can Silicon Valleys artificial meat save the world


Evan McCormack, 19, is sitting in a local cafe staring at a juicy hamburger on the plate in front of EvanMcCormack. It looks like meat and smells like meat. It cuts and even juices like meat, but its not meat. I like its juicy and crisp, he said. I think texture is an important part of it. Pictorial: this hamburger looks like meat and even cuts it up with blood. But does it have enough meat to attract people who love meat? Pat Brown (PatBrown), the chief executive of the vegetarian burger, has an ambitious plan to replace aquaculture by food production technology in 2035. What is his main motive? Environmental Scienceu3002 He regards every cultured animal as a small factory, and believes that his own technology will have a profound impact on the existing meat, fish and dairy industries. This technology is the most subversive technology on the earth, much more influential than fossil fuel production, transportation systems, mining and logging, he claims. The picture shows that Evan McCormack, 19, likes the vegetarian hamburgers juicy and crisp EvanMcCormack. Aquaculture is the main source of greenhouse gases and the largest consumer and polluter of water resources. Livestock production accounts for 18% of the total greenhouse gas emissions, according to the FAO. The International Center for agricultural and Biological Sciences says that animal protein needs 11 times of fossil fuel compared with plant protein. At present, the ancient forests in the Amazon and other areas are being cut down in large numbers to make room for pasture and forage crops. Image shows: in Brazil, large rainforests in the Amazon basin have been replaced by pastures. However, FAO also pointed out that there are more than 1000000000 practitioners in the industry and 1/3 of the worlds protein needs. At the turn of the century, meat production is 2.29 billion tons, but it is expected to increase to 4.65 million tons by 2050. So Mr. Brown has his own job. Its companys TheImpossibleBurger is likely to be welcomed by Silicon Valley environmentalists and vegetarians, but now it is only sold in specific restaurants across the United States. The company produces about 500000 pounds of hamburgers a month at its factory in Oakland and plans to supply supermarkets before 2020. The company is also committed to the development of fish products. The machine produces plant hemoglobin, which is the key ingredient of meat substitutes. The team of biochemists led by Mr. Brown has found a way to mass produce hemoglobin, a vegetable protein similar to blood. This is actually the secret of bringing competitive advantages to vegetarian hamburgers. The team has used gas chromatography-mass spectrometry, texture analysis and other existing techniques to analyze the smell, taste and texture of meat, and then use plant protein to replicate in the laboratory environment. Tests conducted among meat enthusiasts showed that the participants were not able to distinguish between 47% of the difference between vegetarian burgers and meat made by the company, and the company was trying to surpass 50%. Another way to produce meat is to cultivate animal cells in a laboratory environment. Both Silicon Valley companies MemphisMeats and JustInc use this so-called in vitro culture or clean meat method. At Justs lab, ChingyaoYang, an automation engineer, introduced me to robots that speed up molecular interactions. In essence, they are fast tracking molecular formula. Illustration: Automation Engineer ChingyaoYang shows laboratory robot that accelerates meat growth. We are using data and algorithms to increase the possibility of finding molecular formulas, ChingyaoYang points out. Then senior scientist VitorEspiritoSanto showed us a row of containers similar to the refrigerator, filled with animal cells soaked in a growing solution. An artwork at the scene shows such a future. The conveyor belt is full of chicken breast and steak. This is our clean meat production farm, EspiritoSanto said. The scale of the plant is comparable to that of the largest slaughterhouse in the United States. Although there is no dairy cow here, it has a 200 thousand liter bioreactor. Bio cleaning production will produce steak, chicken and other products... You can imagine all meat. He said the company will release the first artificial meat product later in 2018, and will introduce more complex products in the coming years. At last, we will produce Kobe beef and chicken breast... We will achieve that goal, he said. Illustration: MemphisMeats meat products cultivated with animal cells. In the bay area, MemphisMeats is famous for its $18000 clean meatball. CEO UmaValeti told me that the slogan of the company is: better meat, less calories! By planting meat in the laboratory, he hopes to reduce greenhouse gas emissions from meat production by more than 90%. MemphisMeats was supported by Bill Gate (BillGates) and Richard Branson (RichardBranson), with the support of traditional meat supplier Cargill and Tyson food (TysonFoods). The average annual growth rate of the market for meat substitutes is expected to reach 8.4% from 2015 to $5 billion 200 million by 2020, according to AlliedmarketResearch. But can these technology start-ups really bear the strength of the global meat industry? Back to the cafe, Evan McCormack (EvanMcCormack)s father, Richard (Richard) has been a vegetarian for decades, but his enthusiasm for impossible hamburger is less than his son, which he thinks is no difference from other vegetable pies. This is three dollars more expensive than the common hamburger! He complained, why? Because theres a little blood in it?
