Who would want to grow meat in a lab? Well, astronauts on long space flights might be interested, because regular meat would take up a lot of space in a small spacecraft. NASA has shown that just such a thing can be done on a small scale — but maybe we could find some benefits from producing meat on a large scale, large enough that you could buy it at the supermarket. The industry that produces meat from livestock like cows and chickens is very hard on the environment, because it causes pollution. There are also drugs that are given to animals raised for meat that can cause health problems. Also, if we could make our meat in a laboratory, we could replace some of the bad fats that cause cholesterol with healthier kinds of fats. So you see, there are some good reasons that scientists are looking at ways of growing chicken nuggets without the chicken!
