Thursday, hundreds of thousands took to the mall to march in protest of abortion, which stills thousands of tiny beating hearts in America daily. The crowd has become an overwhelmingly young one. So young that the site of the 2010 March for Life prompted the then-departing head of NARAL, Nancy Keenan, to remark, “I just thought, my gosh, they are so young. There are so many of them, and they are so young.”

It should not surprise America that the pro-life movement is growing younger and stronger. Incredible advances in science have made it possible for young women such as myself to first greet our children and witness their miraculous development beginning when they aren’t much bigger than a legume. Today’s women track their baby’s developments with any number of smartphone apps. Today’s children are growing up in a world where ultrasound pictures of their siblings are taped to the family refrigerator. Today’s would-be parents are bringing children into the world where tremendous medical advances keep nudging backward the age at which babies born prematurely can be kept alive.
