1) IMO, if you take Turmoil you oughtta take Luck, so the now increased probability of events will not cause extreme damage (such as lab-burning events etc.).
2) IIRC, CW doesn't kill population that quickly, a mere 1% per turn (again, IIRC), so taking Growth-3 means only 0.1% per turn, so now you have lots of population so taking Turmoil and Sloth becomes a bad thing.

EDIT: Just wanted to add I saw that 1% in some unrelated post, stating AE kills 5% per turn, SG 4% and CW 1%.
