Why do people develop space vegetables?

1, the space environment is very different from the earth's surface environment. Science has been studying that crops planted in space have more nutrients than crops planted on the surface of the earth, and what they will lose. What will happen to the seeds under weightlessness, and will the fruit grow or shrink due to variation? Research and planting on the earth may greatly increase income and improve nutrients.

2. Planet migration is a common topic for everyone, and it is also a preparation for the future. If you can really immigrate to another planet, you have to eat and grow agricultural products. This is also learning in advance.
