WHAT=92S NEW Robert L. Park Saturday, 7 Jan 2012 Washington, DC=20 1. ENVIRONMENTAL DAMAGE: IT=92S PROPORTIONAL TO HUMAN POPULATION. One by one, the great ocean fisheries are being destroyed by overfishing,= =20 including the storied Grand Banks off Newfoundland. Elsewhere, ocean gyr= es=20 (circulations) have trapped gigantic "floating garbage patches," consisti= ng=20 of barely-buoyant pieces of man-made plastics that threaten marine life. = On=20 land, the Green Revolution saved billions of lives from starvation in the= =20 20th century, but at the cost of lower groundwater levels over much of th= e=20 globe and depleted reserves of phosphate rock. It would be impossible to=20 repeat the Green Revolution today. Moreover, population growth pushes oi= l=20 production ever closer to the dreaded Hubbert Peak, even as atmospheric=20 carbon from burning fossil fuel contributes to global warming and lowers=20 the pH of the oceans, with serious environmental consequences. The lesson= =20 is clear: excessive population is damaging our environment at a rate that= =20 far exceeds the natural recovery rate. What then determines the populati= on? 2. FERTILITY RATE: IT=92S PROPORTIONAL TO HUMAN IGNORANCE. World population reached 7 billion in November 2011 and is on track to a=20 disastrous 9 billion by mid-century. This is generally taken to be=20 evidence of a powerful reproductive instinct. There is, to be sure, a=20 nurturing instinct, but who thinks about that during foreplay? The Pill=20 will one day be recognized as the most important invention of the 20th=20 century; it permits us to plan our most essential function: reproduction.= =20 Unfortunately, industry wants more consumers, generals want bigger armies= ,=20 priests want their souls. Fertility in developed nations, however,=20 including all of Europe, is at or below the replacement rate, usually tak= en=20 to be 2.1. This is not the result of some policy consensus; it's simply=20 that access to the Pill now empowers women to develop to their full=20 potential. The lowest fertility rate is in China, where the current=20 economic miracle refutes the belief that a low fertility rate is bad for=20 business. The highest fertility rate of any country is 7.0 in Afghanista= n,=20 where the Sunni Muslim Taliban forbade girls to learn to read. =20 3. REPUBLICAN FERTILITY: IS IT PROPORTIONAL TO POLITICAL SUCCESS? In Rick Santorum=92s marriage, fertility follows the appalling rate of=20 Afghanistan. A father of seven and a Catholic, Santorum described=20 contraception as "a license to do things in a sexual realm that is counte= r=20 to how things are supposed to be." Uh, what sexual things is he talking=20 about and how should they be? With five children of his own, Mitt Romney,= =20 barely edged out Santorum in the Iowa Republican Caucus but trails him=20 slightly in fertility, five being closer to that of Rwanda. The presumpti= ve=20 Democratic presidential candidate has two children. THE UNIVERSITY OF MARYLAND.
