Translation:Decrease is a negative thing.
Could we use 'reduction' here also?
Saluton! Yes, μείωση can be translated as reduction, too.
Dankon tre multe!
Added! Thanks! ;)
Reduction is still not accepted (13 February 2017).
Isn't there a better scientific word for πράγμα than 'thing/object'?
Well, "πράγμα" is no scientific word either, so the translation does the job.
