My friends over in the Auld Country at St. Conleth's Catholic Heritage Association are trying to start a movement to have the responsible figures—perhaps Himself—proclaim a Holy Year for Nuns. Father Tim Finigan at Hermeneutics of Continuity is onboard already; I could kick myself for not picking this up sooner.
I took both formal and informal logic in college, as well as studied social research methods, so I know the difference between a causal link and a correlation. So I don't believe the successes of the "culture of death" over the last forty years were caused by the collapse of the contemplative orders ... but, as a coworker of mine used to say, "What a coinkydink!"
Tim Drake over at National Catholic Register and Msgr. Charles Pope at the Archdiocese of Washington DC, have looked at the numbers from a couple of studies done by the Center for Applied Research in the Apostolate (CARA); both noted that the 2011 report done for the USCCB "ignores the 'elephant in the room'": religious orders emphasizing orthodoxy and tradition, like the Dominican Sisters of Mary, Mother of the Eucharist featured on Oprah, do much better at recruiting new postulants than do the orders that have long since abandoned habits and Catholic devotions. (The DSMME, since their exposure on Oprah Winfrey's talk show, are exploding with new postulants, and are now looking ot expand to California and Texas.)
We need nuns. We need monks and friars, too. Write to your diocesan chancery, and see whom you need to write to, to request a Holy Year for Nuns. Wouldn't hurt to pray for it, either!
