Read the whole thing here.Bemoaning human fecundity has been in vogue at least since 1798, when Thomas Malthus wrote his famous essay arguing that since people multiply faster than the food supply, more babies eventually mean more starvation and misery.
Malthus was wrong (as he later acknowledged), but two centuries later neo-Malthusian misanthropy is as fashionable as ever....
Malthus wrote just before the turn of the 19th century, when the Earth was home to some 980 million human beings. The global population today is about 6.5 billion, a sevenfold increase. If the alarmists are right, our lives should be far more impoverished, degraded, and pitiful than those of our ancestors. But they aren't. By and large, human beings today are healthier, wealthier, safer, cleaner, better fed, and more productive than those who lived in 1800....
Far from being a disaster for our species and the planet... economic growth and technological change have been a boon for both, making it possible for ever more people to live ever-improving lives in an ever-cleaner environment. And while the developed countries may outstrip the developing world in wealth, it is in the world's poorest societies that some of the greatest strides are being made.
Take food. Since 1950, the world's population has soared by more than 150 percent. Yet food has become so abundant that global food prices (in real terms) have plunged 75 percent. Over the past generation, chronic undernourishment in poor countries has been slashed from 37 percent to 17 percent, while in the United States, staples such as potatoes and flour have dropped in price (relative to income) by more than 80 percent.
Or take infant mortality. Before industrialization, children died before reaching their first birthday at a rate exceeding 200 per 1,000 live births, or more than one in five. "In the United States as late as 1900... infant mortality was about 160; but by 2004 it had declined to 6.6." In developing countries, the fall in mortality rates began later, but is occurring more quickly. In China, infant mortality has plunged from 195 to below 30 in the past 50 years.
Life expectancy? From 31 years in 1900, it was up to 66.8 worldwide in 2003.
Health? We are more likely to be disease-free today than our forebears were a century ago. And the onset of chronic illness has been significantly delayed -- by nearly eight years for cancer, nine years for heart diseases, and 11 years for respiratory diseases.
Education, child labor, clean air, freedom, famine, leisure time, global poverty..., by almost any yardstick you choose, humanity thrives as never before. Living standards do not fall as population rises. On the contrary: Where there are free markets and free minds -- economic growth and technology -- human progress and hope are all but guaranteed.
