Nate: 对实验室培育肉类的制作过程感到好奇。 Rachael Floriani: 实验室培育肉类旨在解决全球粮食安全和环境问题，例如减少土地使用、降低碳排放和改善动物福利。该技术通过从动物身上提取少量细胞，在实验室中进行培养，最终生成肉类产品。培养基中包含营养物质，细胞在可食用的海藻和凝固牛奶制成的支架上生长。冷冻干燥技术用于去除培养基中的水分，最终形成肉块。 Jane Lindholm: 当前的肉类生产模式存在诸多问题，例如土地过度使用、环境污染和动物福利问题。实验室培育肉类有望解决这些问题，但同时也面临一些挑战，例如能源消耗和公众接受度。人们对食物的文化和情感联系也是需要考虑的因素。 Lorenzo: 提出人们是否必须吃肉的问题，引发对素食和纯素食选择的讨论。 Rachael Floriani: 实验室培育肉类并非要取代传统肉类，而是提供一种更可持续的替代方案。该技术可以极大地提高肉类产量，减少对土地和资源的依赖。实验室培育的肉类在口感和味道上与传统肉类相似。将实验室的科学方法转化为家庭烹饪的食谱是未来的发展方向。 Jane Lindholm: 未来人们的饮食选择可能包括减少肉类消费、选择植物性肉类替代品或在家中培育肉类。

How is meat made in a lab? That’s what 10-year-old Nate in New Jersey wants to know! Scientists have figured out how to grow meat in laboratories. Some hope lab-grown meat will be able to help address issues like global food insecurity, agricultural pollution and animal cruelty. But 5-year-old Lorenzo in California wants to know why people have to eat meat anyway? But Why visits scientist Rachael Floreani of the Engineered Biomaterials Research Laboratory at the University of Vermont to learn more about how and why lab-grown meat is being developed.
