This is a relatively new industry, although it has many possible applications, its polluting effect is not clear and as it is normal for its effects to be seen in the long term, we can only hope that the advantages outweigh the negative effects for human life on the planet.
Greetings friend @trabajosdelsiglo. Yes, being a relatively new science it is still not clear its long term effects, we need more evidence like this to determine its cumulative effect on people and the environment.
