The preponderance of white dwarfs in the Milky Way were formed from theremnants of stars of the same or somewhat higher mass as the Sun, i.e., fromG-stars. We know that life can exist around G-stars. Any technologicallyadvanced civilization residing within the habitable zone of a G-star will facegrave peril when its star transitions from the main sequence and successivelyenters sub-giant, red giant, planetary nebula, and white dwarf stages. In fact,if the civilization takes no action it will face certain extinction. The twoalternatives to passive extinction are (a) migrate away from the parent star inorder to colonize another star system, or (b) find a viable solution withinone's own solar system. It is argued in this paper that migration of an entirebiological population or even a small part of a population is virtuallyimpossible, but in any event, far more difficult than remaining in one's homesolar system where the problem of continued survival can best be solved. Thisleads to the conclusion that sub-giants, red giants, planetary nebula, andwhite dwarfs are the best possible candidate targets for SETI observations.Search strategies are suggested.
