实验室人造肉来了,来看看它的优缺点
实验室人造肉来了,来看看它的优缺点

By taking cells from a live cow, scientists are now able to actually produce meat inside of a laboratory. Although some people have some doubts about lab meat, it has the potential to change the entire food industry. Let’s examine some of the potential benefits. 

Save Animals. Animal cruelty has always been a big topic in this country. If lab-grown meat becomes popular, it will prevent thousands of farm animals from being killed. People will be able to eat meat with no feelings of guilt. 

      Clean & Natural-Tasting. To the delight of everyone, lab-grown meat does not taste any different from real meat. Most importantly, the nutritional value of the meat is not affected. Lab meat is also a lot cleaner. It is far less likely to become contaminated by pathogens(病原体).

      Much Friendlier to the Environment. One of the biggest problems associated with raising cattle is the large amount of greenhouse gas emissions being produced. You must also factor in the large quantity of water that is needed to keep these animals alive. Land space is yet another very important aspect of raising livestock. Lab meat will help preserve the planet by reducing these issues. 

Why hasn’t lab meat yet become mainstream? Over time, lab meat should gradually become more and more accessible. The current price is obviously a key factor. It costs about $36 a pound, which is more money than most consumers are willing to pay. When companies finally begin to mass-produce the meat, you can expect its cost to become a lot more affordable. People from around the globe will eventually learn about the advantages of clean meat.
