תרגום - איטלקית-אנגלית - tutto ciò che si produce, è prodotto da un altro

Passive voice, natural reduction

Everything that is produced > everything produced

Based on Latin; "Everything that's produced is produced by someone else"

I think, it could be better: "Everything produced, is produced by someone".

I don't know, if the "else" is necessary.

The guy who requested the translation sent to my box (in Spanish)this information:

"Debe ser usado : producido por otro"

Therefore...Everything produced, is produced by others.
Since he said that this others may refer to people or things.
