Would that it could happen, walden. In many cases there simply isn't available space for a crisis pregnancy center to purchase. For example, one of the most infamous abortuaries in the Twin Cities is the Meadowbrook Women's Center, located in the Methodist Hospital complex. No crisis pregnancy center would be allowed to "compete" for babies' lives within that complex.
There are many crisis pregnancy centers in existence, though. Though the listing isn't exhaustive, to my knowledge, there's a CPC Network web site which lists many of those centers in each state and Canada. Minnesota, for example, has 57 listings; they're in small towns, medium-sized cities, and large areas like Minneapolis, St. Paul, Rochester, and Duluth.
Three with which I'm familiar are the Robbinsdale Women's Center (which is located close to an abortuary in the North Memorial Medical Center complex), Alpha Women's Center (in a small suburban community of 12,000), and Cradle of Hope in St. Paul. My wife and I support the latter two and are continually thrilled to hear the reports of babies' lives saved and women helped through crisis pregnancies with gifts of furniture, medical and rent payments, emotional support from caring volunteers, et al.
I know that the Catholic Church is one of the world's richest institutions, and I also know that Protestant churches and televangelists raise billions each year. If the will were there to solve this problem, it could be solved, or at least dramatically reduced.
