Since ancient times, why didn't anyone build prisons in the desert and let prisoners plant trees?

There were many kinds of criminal laws for criminals in ancient times. Some prisoners who are caught will be put into prison, while others will be sent directly to the desolate areas of the border. Some people will think: Why not plant trees in the desert to transform them? This will not waste manpower and material resources, but also transform the desert. Because in ancient times, the distribution places were all poor and backward places, and there were often foreign invasions, these people could be sent to resist foreign enemies, but now it is more humane, because prisons are places to reform people, not just punish them, and building prisons in the desert is not a problem that can be solved in one word, so there will be no such practice.

1. In ancient times, it was illegal for prisoners to be sent to the frontier. In ancient times, prisoners whose crimes were lighter than those sentenced to death and heavier than ordinary prisoners were sent to remote and poor frontiers. The reason why the imperial court did this is because the ancients all had plots in their hometowns, and people who were sent to the frontier could not return to their hometowns to settle down until they died. This is a cruel punishment for criminals. The ancient frontier is a place with few people, poor living conditions and very backward economy, and there are often foreign invasions. These prisoners were sent here to develop production and resist foreign enemies. According to ancient technology, building a prison in the desert is an idiotic thing, so this method is not advisable.

Second, modern prisoners' reform and re-education Nowadays, people have committed crimes, the government is also very humanized, and everyone is equal before the law. In modern prisons, it is not only a place to hold prisoners, but also a place to govern the country according to law. More importantly, this is a place where they can turn over a new leaf and start over. Moreover, it is against the purpose of human nature to keep prisoners in the desert. You should know that planting trees in the desert is no joke. The wrong tree planting method will worsen the desert environment. Moreover, the desert is a terrible place, and people are very small in nature. It is very difficult for people to survive in the desert, and the current technology can't meet such standards.

The main purpose of prisoners' mistakes is not to punish them, but to reform them and turn over a new leaf. As for planting trees in the desert to transform the environment, it is a good thing, but technology can't build prisons in the desert to survive here. The idea of planting trees in the desert is right, but we should use scientific methods to plant trees, because we have learned from the past, and the wrong method of planting trees will make the desert environment worse. I believe that in the near future, the desert will get better and better.
