It will be made in a similar way to brewing beer. We are not talking about a new kind of drink,
however, but describing a new industry aiming to grow meat in the lab. This new food is known as clean meat, cultured meat or cultivated meat.
Demand for meat has never been higher, but the way we produce it today is unsustainable. So scientists around the world are learning to grow meat and seafood in their labs without the need for farms or livestock. They have had considerable success—the world’s first lab-grown beef burger was cooked and tasted in London in 2013, though at a price of around $250,000, but costs have dropped since then. The challenge now is to turn these lab-based successes into food that can be sold on supermarket shelves at reasonable prices.
This revolution is desperately needed. The world’s population is growing, with another 2 billion expected by 2050. Demand for meat is expected to grow by 70 per cent, significantly increasing the pressure on limited resources such as land and water. This in turn will drive climate change. Today, livestock farming is responsible for 15 per cent of global greenhouse gas emissions and is a key cause of deforestation. If meat could be grown in the lab instead of on farms, it could create an alternative to traditionally-produced meat and help reduce the environmental footprint for meat production.
Cultured meat is produced using some of the same technologies biologists have used for decades to grow animal cells. First, muscle cells are taken from live animals, from which stem cells are isolated and then cultured in the lab. The next stage is more difficult, however. The cultured cells must then be grown and separated into a form of tissue comprising of muscle, fat and other cells that is suitable for food processing and consumption. Finally, this tissue will be processed and formed into products such as burger meat, sausages or shrimp meat.
Currently, around 60 start-ups around the world are developing and improving the cultured meat process to make different meats and seafood. And they are all looking to scale up production while bringing down costs. So when will the fruits of this cellular agriculture reach the supermarket shelves? In the next few years we can expect a few launches of small-scale products in high-end restaurants. It will be a pretty expensive burger in a restaurant in Hong Kong or San Francisco, however by 2030 you might see them on supermarket shelves at a decent price.
The first lab-grown beef burger in the world was _________.
选项
A、cooked by scientists in the lab
B、so expensive that did not go into the market
C、sold on the supermarket shelves at a reasonable price
D、a great success even though not affordable for the public
答案
D
解析
细节题。根据题干关键词lab-grown beef burger可定位至第二段第三句“They have had considerable success——the world’s first lab-grown beef burger was cooked and tasted in London in 2013.though at a price of around $250.000.but costs have dropped since then”,即“他们已经取得了相当大的成功——2013年,世界上第一个实验室培育的牛肉汉堡在伦敦接受了烹饪和品尝,当时的价格是25万美元左右,但成本从那时起已经下降了”。根据原文逐个分析四个选项:选项[A]张冠李戴,原文说的是“was cooked and tasted in London”,因此这个汉堡是实验室培育的,不是科学家们烹饪的,排除。选项[B]无中生有,原文并没有提及是否进入市场,排除。选项[C]无中生有,也排除。选项[D]a great success even though not affordable for the public是对原文“They have had considerable success…though at a price of around$250,000”的同义替换,故为正确答案。
