Answer:
The collapse of Rome was a catastrophe for western Europe and western civilization as well.
Rome's fall ended the ancient world and the Middle Ages began. These “Unlighted Ages” brought the end to much that was Roman. The West fell into chaos. Since Rome was no longer a trade hub many commerce routes were not used anymore. The network of roads that Romans had built started to vanish. The drainage system built by Romans suffered the same fate. However, while much was lost, western civilization still owes a debt to the Romans.
