Yet, despite these trends, the world's populace is augmented by 80 million people annually. All of them are born to the younger inhabitants of the more penurious corners of the Earth. There were only 1 billion people alive in 1804. The number doubled a century later. But our last billion - the sixth - required only 12 fertile years. The entire population of Germany is added every half a decade to both India and China. Clearly, Mankind's growth is out of control, as affirmed in the 1994 Cairo International Conference on Population and Development. Dozens of millions of people regularly starve - many of them to death. In only one corner of the Earth - southern Africa - food aid is the sole subsistence of entire countries. More than 18 million people in Zambia, Malawi, and Angola survived on charitable donations in 1992. More than 10 million expect the same this year, among them the emaciated denizens of erstwhile food exporter, Zimbabwe. According to Medecins Sans Frontiere, AIDS kills 3 million people a year, Tuberculosis another 2 million. Malaria decimates 2 people every minute. More than 14 million people fall prey to parasitic and infectious diseases every year - 90% of them in the developing countries. Millions emigrate every year in search of a better life. These massive shifts are facilitated by modern modes of transportation. But, despite these tectonic relocations - and despite famine, disease, and war, the classic Malthusian regulatory mechanisms - the depletion of natural resources - from arable land to water - is undeniable and gargantuan. Our pressing environmental issues - global warming, water stress, salinization, desertification, deforestation, pollution, loss of biological diversity - and our ominous social ills - crime at the forefront - are traceable to one, politically incorrect, truth: There are too many of us. We are way too numerous. The population load is unsustainable. We, the survivors, would be better off if others were to perish. Should population growth continue unabated - we are all doomed. Doomed to what? Numerous Cassandras and countless Jeremiads have been falsified by history. With proper governance, scientific research, education, affordable medicines, effective family planning, and economic growth - this planet can support even 10-12 billion people. We are not at risk of physical extinction and never have been. What is hazarded is not our life - but our quality of life. As any insurance actuary will attest, we are governed by statistical datasets. Consider this single fact: About 1% of the population suffer from the perniciously debilitating and all-pervasive mental health disorder, schizophrenia. At the beginning of the 20th century, there were 16.5 million schizophrenics - nowadays there are 64 million. Their impact on friends, family, and colleagues is exponential - and incalculable. This is not a merely quantitative leap. It is a qualitative phase transition. Or this:
