Much like the Greeks, the Phoenicians left an indelible mark on the ancient world, and their influence has continued to the present day. The most prominent example of this is in the words we type, which had their roots in the Phoenician alphabet. But while Greek culture survives today (albeit in a considerably different form than it had in antiquity), Phoenician culture is - to the best of my knowledge - pretty much dead.
So my challenge is this: ensure Phoenician culture survives to the present day in some form or another.
