How do you distinguish between, "They destroy the forests by fire," and "The forests destroy the fire?"
The latter would use different inflections: "Silvae ignem delent." "Silvae" in the nominative case since it would be the subject, and "ignem" in accusative since it would be the direct object.
Very Bad of them!
Obviously you have never heard the idium "Pax Romana" . Nothing will grow in the area in and around what use to be Carthage to this day. Burning a forest down was just foreplay as far as the Roman's were concerned. Requiescat In Pace. (R.I.P.)
maybe there where to many parrots in it
