Question

【题目】 The UK should start producing lab-grown meat to help solve the world’s food crisis (危机), according to a research group. A report by the Adam Smith Institute says meat made in a laboratory is better for the environment and would be cheaper than meat produced from farm animals.

Need for meat around the world is expected to increase by 70% by the year 2050. So could people be eating lab-grown meat in the future? Usually animals like cows are killed to produce the meat that people eat, but scientists have found a way to make meat in a laboratory without killing any animals.

Animals are made up of cells (细胞). Scientists worked out how to take cells from an animal, like a cow, and multiply (繁殖) them in a dish. In the end from one tiny cell, tens of billions of cells can be grown. These join together to form meat.

In 2013, the first hamburger grown this way was eaten in London. It took a year to produce and cost over 200,000 to make. Dr Mark Post, who created the world’s first hamburger from meat grown in a lab, told the BBC it “tastes exactly the same as the meat we know”. When two food critics (评论家) tried the burger in 2013, one said it was “close to meat” and another said it tasted like a real hamburger. It’s not just beef that is being created; companies are also working on other meat like turkey and chicken.

The Adam Smith Institute says moving away from the present way meat is produced would help reduce greenhouse emissions (排放) by up to 96% and free up 99% of the land used in farming worldwide. They also think it will reduce chances of food poisoning (中毒) because the meat is grown under such controlled conditions. Jamie Hollywood from the Adam Smith Institute also told the BBC lab-grown meat could be a lot cheaper. He says the price has gone down in five years from 200,000 to 8, so in the future it could be even less.
