Ah! now I feel better about any Sundaland scenario.

Anyway, catastrophy or not, as I gather from the text, after about
two thousand years, salination of the Black Sea is complete and, I
surmise, present anoxic conditions ensue. Now this means that
fishing, if any, as a stable dietary source collapses. Famine and
emigration, at the right time for IE languages to disperse. Now this
scenario hinges on PIE speakers getting a large percentage of diet
from fishing. What is the linguistic evidence for PIE fishing?
