From NYTimes.com: No Babies?

In Germany, where the births-to-deaths ratio now results in an annual population loss of roughly 100,000, Ursula von der Leyen, Chancellor Angela Merkel's family minister (and a mother of seven), declared two years ago that if her country didn't reverse its plummeting birthrate, "We will have to turn out the light."

Incredibly fascinating story.  I always tend to think of the planet is getting overcrowded, but in Europe, a shrinking population is a real problem.
