In the last fifty years, the population of the world has increased three times over. Throughout the developing world, children are less likely to be lost to disease. And this new generation can expect to live twenty years longer than their parents' generation. Worldwide, millions of today's newborns will live lives that could span the entire twenty-first century.
But living longer and its attendant rewards have raised unexpected new challenges for medicine and public health: how to maintain a supply of clean water and proper sanitation in the face of a rapidly growing population; how to curb pollution as more and more countries industrialize; and how to keep new strains of -- or antibiotic-resistant -- infectious disease from emerging?
In Living Longer, the people remember: Polio vaccine, March of Dimes and mass inoculation campaigns, World Health Organization, eradication of smallpox in India and Africa, advances in public health, population explosion, family planning, contraception campaigns, AIDS, resurgence of tuberculosis.
